Overview
Page 1 of 8 3932 ADVANCED DATASHEET - 03/02/99 (Subject to change without notice) 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 r...
