A3932SEQ General Description

The A3932SEQ is a three-phase MOSFET con trol ler for use with bipolar brushless dc motors. Its high gate-current drive capability allows driving a wide range of n-channel power MOSFETs and can support motor supply voltages to 50 V. Bootstrapped high-side drive blocks provide the fl oat ing positive supplies for the gate drive and minimize the component count normally required. The high-side cir cuit ry also em ploys a unique FET monitoring circuit that ensures the gate voltages are at the proper levels before turn-on and during the ON cycle.

Internal fi xed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. The peak loadcurrent limit is set by the user's selection of an input reference volt age and external sensing resistor. The fi xed off-time pulse duration is set by a user-selected external RC timing network. For added fl exibility, the continued ...
