FUNCTIONAL PIN DESCRIPTION
Freescale Semiconductor, Inc...
VB
This pin provides a node for charge storage at the boost voltage. Internal circuitry will draw VB current from this node, and the charge pump will deliver charge to this node.
DATA
This logic input is the serial data used by the serial interface.
CLOCK
This logic input is the clock for the serial interface. Data is shifted in synchronously with this clock.
CP1 and CP2
These pins are the connections to the switching capacitor in the charge pump. These pins swing between ground and VB, drawing charge from VBB and delivering it to the VB node.
STROBE
This logic input is used to latch data from the serial interface into the internal logic.
DIR
This is the direction input for the H-bridge driver.
VREF
This input provides a reference voltage for the current limit comparator threshold.

FUNCTIONAL DESCRIPTION Serial Interface
The 34923 is controlled via a 3-wire (clock, data, strobe) serial port. The programmable functions allow maximum flexibility in configuring the PWM to the motor drive requirements. The serial data is clocked in starting with bit D19. Bit D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 D16 D17 D18 D19 Function Blank Time LSB Blank Time MSB Fixed Off-Time LSB Fixed Off-Time Bit 1 Fixed Off-Time Bit 2 Fixed Off-Time Bit 3 Fixed Off-Time MSB Fast Decay Time LSB Fast Decay Time Bit 1 Fast Decay Time Bit 2 Fast Decay Time MSB Synchronous Rectification Mode Synchronous Rectification Enable External PWM Decay Mode Enable Logic Direction Logic Divisor SPAN Select Internal PWM Mode Test Mode Sleep Mode
D2-D6, Fixed Off-Time
A five-bit word sets the fixed off-time for internal PWM current control. The off time is defined as follows: t off = (8[1 + N] /fosc) - 1/f osc where N = 0 to 31. For example, with an oscillator frequency of 4.0 MHz, the offtime is adjusted from 1.75 s to 63.75 s in increments of 2.0 s.
D7-D10, Fast Decay Time
A four-bit word sets the fast decay portion of the fixed off-time for the internal PWM control circuitry. This will only have impact if the mixed current decay mode is selected (via bit D17 and the PWMMODE input pin). For t fd > t off, the device will effectively operate in the fast decay mode. The fast decay portion is defined as follows: t fd = (8[1 + N]/f osc) - 1/fosc where N = 0 to 15. For example, with an oscillator frequency of 4.0 MHz, the fast decay time is adjusted from 1.75 s to 31.75 s in increments of 2.0 s.

D11-D12, Synchronous Rectification Control
The active mode prevents reversal of load current by turning off synchronous rectification when a zero current level is detected. The passive mode will allow reversal of current but will turn off the synchronous rectifier circuit if the load current inversion ramps up to the current limit set by VREF /RS. D11 0 0 1 1 D12 0 1 0 1 Synchronous Rect. Control Disabled Active Disabled Passive

Bit D14, in conjunction with the PWM/ENABLE pin, determines if the output drivers are in the chopped (OFF) or ON state. PWM/ ENABLE 0 1 1 0 D14 0 1 0 1 Operating Mode Chopped ON
D19, Sleep Mode
Bit D19 selects a Sleep mode to minimize power consumption when not in use. This disables much of the internal circuitry, including the regulator and charge pump. On power-up the serial port is initialized to all zeros. Bit D19 should be programmed high for 1.0 ms before attempting to enable any output driver. D19 0 1 Sleep Mode Sleep Normal

Freescale Semiconductor, Inc...
D15, Direction Logic
Bit D15, in conjunction with the DIR pin, determines if the device is operating in the forward or reverse state. State Reverse Forward DIR 0 1 1 0 D15 0 1 0 1 DCMA Low High DCMB High Low
Data is clocked into the shift register on the rising edge of the CLOCK signal. Normally STROBE will be held high, only brought low to initiate a write cycle. Refer to Figure 2, Serial Port Write Timing, page 8, for the minimum timing requirements.
VREG
This internally generated voltage is used to operate the sinkside outputs. The VREG pin should be decoupled with a 0.22 F capacitor to ground. VREG is internally monitored and, in the case of a fault condition, the outputs of the device are disabled.
D16, Divisor SPAN Select
Bit D16, in conjunction with the SPAN pin, determines if VREF is divided by 5 or 10. Divisor /5 /10 SPAN 1 0 0 1 D16 0 1 0 1
Charge Pump
The charge pump is used to generate a gate supply voltage greater than VBB to drive the source-side gates. A 0.22 F ceramic capacitor should be connected between CP1 and CP2 for pumping purposes. A 0.22 F ceramic capacitor should be connected between VB and VBB to act as a reservoir to operate the high-side devices. The VB voltage is internally monitored and, in the case of a fault condition, the source outputs of the device are disabled.
Shutdown
In the event of a fault (excessive junction temperature or low voltage on VB or VREG), the outputs of the device are disabled until the fault condition is removed. At power-up, and in the event of low VDD, the Undervoltage Lockout circuit disables the drivers and resets the data in the serial port to all zeros.
D17, Internal PWM Mode
Bit D17, in conjunction with the PWMMODE pin, selects mixed or slow current decay. PWMMODE 0 1 1 0 D17 0 1 0 1 Current Decay Mode Mixed Slow
PWM Timer Function
The PWM timer is programmable via the serial port (bits D2- D10) to provide off-time PWM signals to the control circuitry. In the mixed current-decay mode, the first portion of the off time operates in fast decay, until the fast decay time count (serial bits D7-D10) is reached, followed by slow decay for the rest of the off-time period (bits D2-D6). If the fast decay time is set longer than the off time, the device effectively operates in fast decay mode. Bit D17, in conjunction with PWMMODE, selects mixed or slow decay.
D18, Test Mode
Bit D18 low (default) operates the device in normal mode. D18 is only used for testing purposes. The user should never change this bit.

PWM Blank Timer
When a source driver turns on, a current spike occurs owing to the reverse recovery currents of the clamp diodes and/or switching transients related to distributed capacitance in the load. To prevent this current spike from erroneously resetting the source-enable latch, the sense comparator is blanked. The blank timer runs after the off-time counter (see bits D2-D6) to provide the programmable blanking function. The blank timer is reset when PWM/ENABLE is chopped or DIR is changed. For external PWM control, a DIR change or PWM/ENABLE on will trigger the blanking function.
Current Regulation
Load current is regulated by an internal fixed off-time PWM control circuit. When the outputs of the H-bridge are turned on, the current increases in the motor winding until it reaches a trip value determined by the external sense resistor (RS), the applied analog reference voltage (VREF), the SPAN logic level, and serial data bit D16: When SPAN = D16, ITRIP = VREF /10RS When SPAN D16, ITRIP = VREF /5RS At the trip point, the sense comparator resets the sourceenable latch, turning off the source driver. The load inductance then causes the current to recirculate for the serial-portprogrammed fixed off-time period. The current path during recirculation is determined by the configuration of slow/mixed current-decay mode (D17) and the synchronous rectification control bits (D11 and D12).
Synchronous Rectification
When a PWM off cycle is triggered, either by an PWM/ ENABLE chop command or internal fixed off-time cycle, load current will recirculate according to the decay mode selected by the control logic. The 34923 synchronous rectification feature will turn on the opposite pair of outputs during the current decay and effectively short out the body diodes with the low RDS(ON) driver. This will reduce power dissipation significantly and can eliminate the need for external Schottky diodes. Synchronous rectification can be configured in active mode, passive mode, or disabled via the serial port (bits D11 and D12). The active or passive mode selection has no impact in slowdecay mode. With synchronous rectification enabled, the slowdecay mode serves as an effective brake mode.
Freescale Semiconductor, Inc...
Internal PWM (Current Mode) PWM Frequency
The internal PWM opeating frequency is set by the sum of "Off Time", as determined by bits D2 through D6, "Blank Time", as determined by bits D0 and D1, and the time constant of the motor.

APPLICATIONS Current Sensing
To minimize inaccuracies in sensing the ITRIP current level, which may be caused by ground trace IR drops, the sense resistor should have an independent ground return to the ground pin of the device. For low-value sense resistors, the IR drops in the PCB sense resistor's traces can be significant and should be taken into account. The use of sockets should be avoided because they can introduce variation in RS owing to their contact resistance. The maximum value of RS is given as RS 0.5/ITRIP.
Layout
The printed wiring board should use a heavy ground plane. For optimum electrical and thermal performance (see following Note), the driver should be soldered directly onto the board. The ground side of RS should have an individual path to the ground pins of the device. This path should be as short as is possible physically and should not have any other components connected to it. It is recommended that a 0.1 F capacitor be placed between SENSE and ground as close to the device as possible; the load supply pin, VBB, should be decoupled with an electrolytic capacitor (>47 F is recommended) placed as close to the device as is possible. Note The thermal resistance and absolute maximum allowable package power dissipation specified in the MAXIMUM RATINGS table, page 4, is measured on typical two-sided PCB with minimal copper ground area. For the 34923, RJA can be reduced to 56C/W with 3.57-in2 copper ground area, as shown in Figure 3.
ALLOWABLE PACKAGE POWER DISSIPATION WATTS
Freescale Semiconductor, Inc...
Braking
The braking function is implemented by driving the device in slow-decay mode via serial port bit D13, enabling synchronous rectification via bit D12, and chopping with the combination of D14 and the PWM/ENABLE input pin. Because it is possible to drive current in either direction through the drivers, this configuration effectively shorts out the motor-generated back EMF (BEMF) as long as the PWM/ENABLE chop mode is asserted. It is important to note that the internal PWM currentcontrol circuit will not limit the current when braking, because the current does not flow through the sense resistor. The maximum brake current can be approximated by VBEMF/RL. Care should be taken to ensure that the maximum ratings of the device are not exceeded in worst-case braking situations of high-speed and high-inertial loads.

Thermal Protection
Circuitry turns off all drivers when the junction temperature reaches 165C typically. It is intended only to protect the device from failures owing to excessive junction temperatures and should not imply that output short circuits are permitted. Thermal shutdown has a hysteresis of approximately 15C.
