THREE PHASE POWER  
MOSFET CONTROLLER  
The A3932SEQ is a three-phase brushless DC motor controller. The  
A3932’s high current gate drive capability allows driving of a wide range of  
power MOSFETs and can support motor supply voltages from 12 to 50V.  
The A3932 integrates a bootstrapped high side driver to minimize the  
external component count required to drive N-channel MOSFET drivers.

Internal fixed off time PWM current control circuitry can be used to  
regulate the maximum load current to a desired value. The peak load current  
limit is set by the user’s selection of an input reference voltage and external  
sensing resistor. The fixed off time pulse duration is set by a user-selected  
external RC timing network. For added flexibility, the PWM input can be  
used to provide speed/torque control, allowing the internal current control  
circuit to set a maximum current limit.

The A3932 includes optional synchronous rectification. This feature  
will short out the current path through the power MOSFETs intrinsic body  
diodes during PWM off cycle current decay. This can minimize power  
dissipation in the MOSFETs, eliminate the need for external power clamp  
diodes, and potentially allow a more economical choice for the MOSFET  
drivers.

The A3932 provides commutation logic for Hall sensors configured  
for 120-degree spacing. The Hall input pins are pulled up to an internally  
generated 5V reference. Power MOSFET protection features includes gate-
