A3932 Three-Phase Power MOSFET Controller

RESET. A logic input that enables the device, internally pulled up to LCAP. Logic HIGH will disable the device and turn off MOSFETs, coasting the motor. Logic LOW will enable gate drive to follow commutation logic. This input will override BRAKE. GLC/GLB/GLA. Low side gate drive outputs for externa.
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 curr.
