3932
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-
source voltage monitor, bootstrap capacitor charging current monitor,
undervoltage monitor, motor lead short to supply or ground, and thermal
shutdown.
