FUNCTIONAL DESCRIPTION The STCC05 is a control circuit embedding most of the analog & power circuitry of an air conditioner or refrigirator control module. It interfaces the micro-controller MCU with the AC power and cooling process sections. The voltage supply The 5V voltage regulator supplies the micro-controller MCU. Its input voltage ranges from 7V to 18V; and its average DC output current up to 50mA. With an output filtering capacitor of 100F, its output voltage accuracy is better than +/- 5% in the whole operating range of the ambient temperature TAMB, the load current IDD and the input voltage VPS , contributing directly to the ADC accuracy. The regulator includes also an over current limiter and a thermal shutdown. The over current limiter protects the regulator against output short circuits and inrush currents during the power up. The current limiter is made of a serial shunt resistance as current sensor and a circuit that regulates the input current. Moreover, the thermal shutdown protects the whole circuit against overload operations. It is made of a thermal sensing junction and a hysteresis comparator that is able to switch off the passing element.

The reset circuit This circuit ensures a Low Voltage Detection (LVD) of the output of the regulator. Most micro-controllers have an active RESET pin in the low state: so, the /RST pin will be active at low state. The reset comparator senses the regulator voltage VDD. The /RST pin goes high when VDD is higher than the high threshold VH = 3.75V and after a delay time TUP; and is low when the VDD decreases below the low threshold VL = 3.4V after the delay time TDW. These delays are set by an external capacitor CUP connected to the /RST pin and depend on the trigger thresholds of /RST: For CUP = 100nF, TUP= 400s with VTH= VH/2; TDW= 200s with VTH= VL/2. The Zero Voltage Synchronization ZVS circuit The Zero Voltage Synchronization ZVS circuit generates the signal ZVS that synchronizes the whole operation with the AC line cycle (20 ms on 50 Hz or 16.7 ms on 60 Hz). This signal allows the MCU to control the AC loads and achieve the timing functions. The input pin SYN is an image of the mains voltage. It is connected to either the power supply transformer through a resistor RZV or an opto-coupler that is controlled directly by the AC line voltage. The circuit is protected against fast line transient voltages: a robust ESD protection and a 30s digital filter are implemented to provide a higher immunity to the MCU operation. Its output signal ZVS is inverted respect to the input signal VSYN.

The relay coil drivers These robust circuits allow a DC relay coil to be driven by an MCU output. The relay coil has a minimum resistance of 580 and has a power up to 0.25W for VPS = 12 V. These characteristics are representative of 3A relays such as FTR-F3AA-12V or JQ1A-12V series. The output stage is made of a transistor and a demagnetization diode. The transistor is referred to the ground COM, has a DC current rating of 50mA; and its collector is connected to the output RLI (I=1, 2, 3). The diode is connected between the output pin RLI and the supply pin VPS. Moreover, a fourth coil driver has an extended 150mA current capability to be able to drive the coil of a relay having a 130 minimum resistance and a 1.1W maximum power. These characteristics are representative of 20A relays such as G4A-E-DC12, OMIF-S-112 or UKH12S series.

The buzzer driver with enable control The MCU can excite a warning buzzer with a 50% PWM signal. The buzzer driver amplifies this signal in current and translates it from the 5V MCU output to the VPS supply to produce the right sound level from the buzzer. The output stage is made of a NPN transistor, a PNP transistor and two 1k resistors. The NPN transistor, referred to the power ground COM, is controlled by the input INBZ; its collector is connected to the output BZ1. The input INBZ is driven by a simple push-pull MCU buffer. The PNP transistor, referred to the VPS polarity, is controlled by the input ENBZ; and its collector is connected to the output BZ2 through a 1k resistor. The input ENBZ is driven by a simple push-pull MCU buffer. The pin BZ2 is the supply terminal of the buzzer; and the circuit has a DC current rating of 9mA and the PWM section runs from 10Hz up to 5kHz. A 1k resistor RBZ is connected between the BZ1 and BZ2 pins to discharge the buzzer periodically. Moreover, the addition of an external capacitor-resistor network on BZ2 pin will allow the buzzer to turn on and off smoothly when the pin ENBZ is toggling.
The speed sensor level shifter The OUTS signal is generated by an electronic signal such as the indoor fan speed clock issued of a Hall Effect sensor or a door switch signal and is transmitted to the MCU. As the INS input may be disturbed; a spike suppressor and a simple EMI filter are added to increase the input robustness. The output signal OUTS is not inverted with respect to the input signal INS.

AIR CONDITIONER APPLICATION CONSIDERATIONS
IMMUNITY IMPROVEMENT OF STCC05 AND THE MICROCONTROLLER Some basic rules can be applied to improve the STCC05 immunity in its application:
- The power ground of VPS should be split from the signal ground of VDD, - The STCC05 is placed as close as possible of the MCU, - The supply capacitors would increase the system immunity by being placed closed to the blocks they feed, or putting decoupling capacitors (f.i. CDD = CPS = 100nF) - Large supply wire on the PCB should be avoided to reduce sensitivity to radiated interferences. - A decoupling capacitor can be put on the pin INS of the speed sensor interface and the MCU reset pin (f.i. CINS = 10nF; CUP = 100nF).

Depending of the PCB layout quality, others capacitors may be put on sensitive pins such as the output regulator pin VDD and the zero crossing synchronization input pin SYN.

STCC05 ELECTROMAGNETIC COMPATIBILITY Standards such as IEC61000-4-x evaluate the electromagnetic compatibility of appliance systems. To test the immunity level of the STCC05 to the IEC61000-4-4 (Electrical Fast Transient Bursts), a board representative of usual application control unit should be considered by applying the immunity design rules defined in the previous paragraph. IEC61000-4-4 test does not allow any measurement equipment to be connected to the tested system, as it would corrupt the test results. That is why this board should include a remote monitoring circuit based on optic fibers. Thus, without any electrical link with an oscilloscope, it is possible to monitor the VDD voltage as well as the /RST or the ZVS outputs of the STCC05, during the IEC61000-4-4 test. This optical link detects parasitic commutations of outputs as short as 60ns. With this board, and the burst generator coupled to the mains as specified in the IEC61000-4-4 standard (see the following principle diagram), the STCC05 has been tested successfully at 4kV.

The main heat sources of the circuit during operation are the voltage regulator and the relay coil drivers. Depending of the power supply voltage VPS, the ambient temperature TAMB, and the thermal of resistance of the package Rth(j-a), the sum of all the coil driver currents IM is linked to the output regulator current IDD. In order to avoid spurious thermal shutdown of the system, it is advised to respect this relationship as shown on figures 7 and 8.
EXTENSION OF THE REGULATOR CURRENT CAPABILITY The output current capability of the STCC05 voltage regulator can be increased in a cost effective manner by adding an external ballast transistor and two biasing resistors. With such a circuit, the output voltage regulation remains at 5V 5%, and the current limitation is still active. Such a topology generates also power losses in the external power transistor especially when the supply voltage VPS is high or the regulator is in current limiting mode. Therefore it is advised to use a package with a suitable thermal resistance (Rth j-a). An example is proposed in the following figure doubling the regulator current capability of the solution to 100mA while producing a current limitation typically at 110mA.

FLOATING BUZZER OPERATION The sound produced by the buzzer is controlled by the frequency of the square signal applied to the INBZ input pin. The external RS CS network connected to the BZ2 output pin produces a soft sound by smoothing the buzzer supplying envelope at power up and power down. Contrary to basic drivers, which directly apply
9/13
STCC05-B
the voltage to the buzzer, this circuit feeds the buzzer with the exponential voltage induced by the charge and the discharge of the RS CS network. The ROH and RS resistors contribute to reduce high harmonic sound distortions. Indeed, they limit the peak current through the buzzer, feed the buzzer with the CS capacitor voltage, and limit the current through the low side NPN transistor of the driver. Therefore to set rising/falling durations of the sound shape, it is advised to adjust only the value of the CS capacitor. The integrated RBZ resistor is selected to discharge the buzzer when the low side transistor is off, especially at the maximum operating frequency. The buzzer is completely discharged within five times the time constant of the resistor-buzzer with = RBZ x CBUZZER. Therefore, RBZ < 1 / (10 x FMAX x CBUZZER). Since the buzzer capacitance CBUZZER is about 20nF at the maximum operating frequency of driver is 5kHz, this RBZ resistance is set at 1k.

ZERO CROSSING DETECTION CIRCUITS The detection of the zero crossing of the AC line voltage can be achieved at least on two ways with the STCC05, depending of the power supply unit. When the power supply uses a magnetic 50/60Hz transformer, the input pin SYN is connected to a transformer output through a resistor RZV, the electrical path being closed by the low side bridge diodes.

The delay between the real Zero Crossing event and the falling edge of ZVS depends on the internal filtering time, the resistance RZV, the rectifier drop voltage VF, the VPS supply load and the temperature. The STCC05 contribution to this delay can be evaluated by measuring the delay between its input voltage VTF and its output voltage VZVS. When using VF = 0.8V, RZV = 15k, VPS = 15V, ICC = 20mA, it is about 50 s on rising voltage VTF and 115 s on falling voltage VTF. When the power supply uses a switch mode power supply, the input pin SYN is synchronized by an opto-coupler, which is connected to the mains terminals through high resistances. The isolator output is on all the time except during the zero crossing where no more current feeds the input and the output transistor switches off.

STCC05-B
Finally, the opto-coupler could be connected directly in high side mode between the SYN and the VDD pins: the ZVS signal is then made of high level pulses synchronized with the zero crossing. However, the coupler could be connected in low side mode with an external 10k pull-up resistor to VDD: the ZVS is now inverted with low level pulses.
