THREE-PHASE POWER

MOSFET CONTROLLER

The A3933SEQ is a three-phase MOSFET controller for use with

bipolar brushless dc motors. It drives all n-channel external power

FETs, allowing system cost savings and minimizing r_(DS)onpower loss.

The high-side drive block is implemented with bootstrap capacitors at

each output to provide the floating positive supply for the gate drive.

The high-side circuitry also employs a unique “intelligent” FET

monitoring circuit that ensures the gate voltages are at the proper levels

before turn-on and during the ON cycle. This device is targeted for

applications with motor supplies from 12 V to 28 V.

GHB

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.

A power-loss braking circuit brakes the motor on an under-voltage

condition. The device is configured to either coast or dynamically

brake the motor when this occurs.

The A3933SEQ is supplied in a 32-lead rectangular (9 x 7) plastic

chip carrier (quad pack) for minimum-area, surface-mount applica-

tions.
