TDA3683
Multiple voltage regulator with switch and ignition buffer
Rev. 02 -- 7 October 2005 Product data sheet
1. General description
* The TDA3683 is a multiple output voltage regulator with a power switch and an
ignition buffer. Several protections and diagnostic options are incorporated in this design.
* The TDA3683 is primarily developed to cover the complete power supply
requirements in car radio applications.
* The standby regulators (regulators 1, 2 and 3) are especially designed to supply
digital circuitry that has to be permanently connected e.g. Controller Area Network (CAN) bus, Digital Signal Processor (DSP) core and the microcontroller. In combination with the reset delay capacitor (pin RDC1 or pin RDC2/3) and the reset function (pin RST1 or pin RST2/3), a proper start-up sequence for a microcontroller is guaranteed. The storage capacitor (pin STC) makes the standby regulator outputs insensitive for short battery drops (e.g. during engine start-up).
* The switched regulators (regulators 4, 5, 6 and 7) are intended to be used as supply
for the tuner, logic, sound processor and CD / tape control.
* The power switch (pin PSW) can be used for switching the electrically powered
antenna, display unit and CD / tape drives.
* The ignition buffer is intended to produce a clean logic output signal when a polluted
ignition key signal is used as input.

7. Functional description
The TDA3683 is a multiple output voltage regulator with a power switch and ignition buffer. The device is primarily intended for use in car radio applications. An overall functional description of the building blocks is given in the following sections.
7.1 Standby regulators
The standby regulators (pins REG1, REG2 and REG3) are used for digital circuitry that has to be permanently connected to a supply voltage (e.g. CAN bus DSP core or microcontroller). REG1 is controlled by its own active HIGH enable input (EN1). REG2 and REG3 have a combined enable input (EN2/3) with similar logic properties. Permanent voltage tracking will exist between REG2 and REG3 during power-up and power-down. All standby regulators have a low quiescent current and will not be switched off during thermal shutdown and load dump conditions. The outputs are protected against overload and short-circuit conditions by a current limit / foldback protection.
7.2 Switched regulators
The switched regulators (pins REG4, REG5, REG6 and REG7) are activated by the active HIGH mode input. The regulators are protected against overload and short-circuit conditions by a current limit / foldback protection. They will be switched off during thermal shutdown and load dump conditions. The output voltage of REG7 can be adjusted (2.4 V to 10 V) by using two external resistors connected between the regulator output, the feedback input and ground; see Figure 10. REG7 has a built-in flyback clamp for use in case of inductive loads.

7.3 Power switch
The power switch (pin PSW) is activated by the MODE input. It is switched off during thermal shutdown and load dump conditions. The power switch output voltage is internally clamped at 16 V to protect connected application circuitry (e.g. display and CD / tape drives). The power switch has three different output current modes, depending on its output voltage, the reset capacitor (RDC1) and the junction temperature (i.e. high current, low current and foldback protection); see Figure 7. In the event of an overload the power switch can maintain the maximum output current for a limited period of time (determined by the integration time of the reset delay capacitor) before it drops back to the lower output current capability. This functionality is implemented to prevent, in case of loads such as light bulbs, relays or electrical motors, the power switch from folding back on momentary high inrush currents. In the event of junction temperatures above 150 C, the power switch will drop back to the lower output current capability.The power switch has a built-in flyback clamp for use in case of inductive loads.
7.4 Enable and mode inputs
The enable inputs (pins EN1 and EN2/3) are used to switch on or switch off the standby regulators. The mode input (MODE) is used to enable the switched regulators and the power switch. When all of these inputs are LOW the circuit is in Sleep mode and only the enable detection circuit and the supply overvoltage protection circuit are active. In Sleep mode the device draws a very small quiescent current from the supply. When at least one of the enable inputs is activated the circuit will operate in Standby mode. When the mode input is activated the on condition will be established; before the MODE pin can be activated at least one of the standby regulators must be activated. The enable and mode inputs are 3.3 V and 5 V CMOS logic compatible. A detailed description of the enable and mode pin dependencies is given in Table 4.

7.5 Storage capacitor
The storage capacitor (pin STC) is used as a back-up supply for the standby regulators when the battery (pins VP1 / VP2) can no longer provide the supply. This situation may occur for cold weather engine starts. The rising and falling storage capacitor voltage threshold levels determine if the standby regulators can be switched on. The storage capacitor pin is not intended to be used as an output (e.g. supply switch). No external load should be connected to this pin.
7.6 Reset delay capacitors
The reset delay capacitors (pins RDC1 and RDC2/3) are used to delay the reset pulse (RST1 and RST2/3) starting from the time the associated standby regulator output voltage comes within its regulated voltage range i.e. crosses the rising reset threshold level. An internal current source is used to charge the reset delay capacitor. The reset output will be released (output goes HIGH) when the voltage on the reset delay capacitor crosses the rising threshold level. If the associated standby regulator voltage drops out of its regulated voltage range (drops below its falling reset threshold level) the reset delay capacitor will be discharged with a relatively high sink current. The reset output will be activated (output goes LOW) when the reset delay capacitor crosses the falling threshold level. This feature is included to secure a smooth start-up of the microcontroller at first connection, without uncontrolled switching of the relevant standby regulators during a start-up sequence. It should be noted that RDC1 is also used as a time constant for the delayed current protection of the power switch.
7.7 Reset outputs
The reset function depends on the reset delay capacitor voltage and includes hysteresis to avoid oscillation at the threshold level. The reset outputs are push-pull for sourcing or sinking current. The output voltage can be switched between the ground level and the output voltage of the relevant standby regulator. An external reset delay capacitor can be added if a timed reset pulse is required (CRDC1 or CRDC2/3). Standby regulator 1 has an independent reset function (pins RST1 and RDC1). Standby regulators 2 and 3 have combined circuitry (pins RST2/3 and RDC2/3). The reset trigger signals from both regulators are connected using an OR function to the reset output buffer thus ensuring that both regulators can generate a reset when appropriate. The RST1 output is linked to standby regulator 1 (5 V) and, therefore, generates a 5 V HIGH-level output voltage. The RST2/3 output is linked to regulator 2 (3.3 V) and, therefore, generates a 3.3 V HIGH-level output voltage.
7.8 Hold output
The hold output (pin HOLD) is a combined output for the thermal pre-warning signal and all other diagnostic signals. To distinguish between these signals, the HOLD output is designed as an active HIGH 3-state output buffer. When a no failure condition is present the output is LOW. When a thermal pre-warning signal is generated (e.g. to shut down other circuits in the radio before the regulator itself shuts down) the signal rises to its MID

level. In all other warning situations, the HOLD output rises to its HIGH level. In order to generate standard CMOS logic compliant signals an external decoding circuit has to be implemented; see Figure 9. The HOLD output will be active HIGH when:
* The output voltage of one or more switched regulators is out of regulation (except
REG7), due to overload or supply voltage drops
* * * *
The power switch operates in the Foldback mode In Standby or On mode the thermal shutdown is activated In Standby or On mode the load dump protection is activated In Standby mode a low battery voltage occurs (VP1) indicating that it is not possible to pull REG4 into regulation when switching it on.
It should be noted that there is intentionally no out-of-regulation detection for REG7 since it can be adjusted to maximum 10 V and would, in that event, activate the HOLD signal very early. The HOLD function includes hysteresis in order to avoid oscillations when the hold threshold level is crossed. A schematic diagram of the HOLD function is illustrated in Figure 3.

7.9 Ignition buffer
The ignition buffer (pins IGNIN and IGNOUT) is an independent inverting open-collector output buffer circuit that can be used to sense the start line of the ignition key in a car. The start line will only be pulled-up to the battery voltage in the event of an engine crank resulting in a LOW at the inverting output of the ignition buffer. This output signal can be used to immediately mute an audio amplifier during the engine crank. To guarantee a reliable LOW output signal, even in extreme cold weather crank conditions (the battery voltage may momentarily drop down to 3 V) a low supply latch function is implemented. To make the ignition buffer input robust, for possible extreme transients present on the battery line, an input RC filter is strongly advised. A blocking diode is also recommended to prevent substrate injection in case of negative voltage spikes at the input.
7.10 Supply voltage inputs
The supply voltage inputs (pins VP1 and VP2) are intended to be connected to the battery. Both inputs are protected against load dump transients and reverse battery connections. The second supply pin (VP2) is internally connected to the high current/ low output voltage switched regulators (REG5 and REG6) and can be connected to an external DC-to-DC downconverter for reduced power dissipation and increased power supply efficiency. Power must be applied to pin VP1 to ensure that the circuits are functional, since the band gaps for the switched and standby regulators are connected to this supply pin. Rising and falling supply voltage threshold levels determine if the switched regulators and power switch can be switched on. The timing diagrams for various regulator functions are illustrated in Figure 4 and Figure 5.

11.1 Application notes * A ceramic capacitor of 220 nF must be connected to both supply pins to guarantee
stability over the ambient temperature range. For improved noise performance it is also recommended to connect a standard electrolytic capacitor of 2200 F close to the supply pins.
* A ceramic capacitor of 220 nF must be connected to the storage capacitor pin when
the back-up function is not used to guarantee stability over the ambient temperature range. There are basically no restrictions for the maximum value of the storage capacitor, but the required value depends on the actual output currents of the three standby regulators and the length of time that their outputs must be maintained after the supply voltage collapsed (VP1 = VP2 = 0 V).
* A standard electrolytic capacitor of 10 F, or more, must be connected to the output of
the power switch to guarantee stability over the ambient temperature range. A ceramic capacitor of 100 nF can be added in parallel with the electrolytic capacitor to provide improved HF performance.
* An electrolytic capacitor of 10 F, or more, must be connected to each regulator
output to guarantee stability over the ambient temperature range. There are restrictions concerning the maximum ESR of the electrolytic capacitors that are used; see Table 8. Usually the nominal value of electrolytic capacitors increases and the ESR decreases with temperature so the worst case condition for stability (i.e. minimum capacitance and maximum ESR) exists at low temperatures. Depending on the specified temperature range of the radio set, some of the regulator outputs may need low ESR type electrolytic or tantalum capacitors. A ceramic capacitor of 100 nF can be added in parallel with the electrolytic or tantalum capacitor to provide improved HF performance. However, in the case of the standby regulators (REG1 to REG3) these additional ceramic capacitors should preferably not be connected very close to the device pins to avoid stability issues.

* The output voltage of regulator 7 can be adjusted between 2.4 V and 10 V using two
external resistors (R1 and R2); see Figure 10. The following equation can be used for global calculations to determine the output voltage at a given value of R1 and R2:
R1 V REG7 = 1.2 x 1 + ------ R2
To meet an overall accuracy of 5 % the external resistors should have a 1 % tolerance and the total resistance of the external resistors should have a value maximum 2 k. In the event that no external resistors are used the output voltage will be determined only by the internal feedback resistors. The output voltage will be as follows: Vo = 10 V (5 %).

13. Soldering
13.1 Introduction to soldering through-hole mount packages
This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board.
13.2 Soldering by dipping or by solder wave
Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 C or 265 C, depending on solder material applied, SnPb or Pb-free respectively. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.
13.3 Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 C and 400 C, contact may be up to 5 seconds.

Suitability of through-hole mount IC packages for dipping and wave soldering methods Soldering method Dipping suitable Wave suitable suitable [1] not suitable
For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. For PMFP packages hot bar soldering or manual soldering is suitable.
