A3932

Three-Phase Power MOSFET Controller

Features and Benefits

Description

▪ Drives wide range of N-channel MOSFETs

▪ Synchronous rectification

The A3932 is a three-phase MOSFET controller 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 floating

positivesuppliesforthegatedriveandminimizethecomponent

countnormallyrequired.Thehigh-sidecircuitryalsoemploysa

uniqueFETmonitoringcircuitthatensuresthegatevoltagesare

at the proper levels before turn-on and during the ON cycle.

▪ Power MOSFET protection

▪ Adjustable dead time for cross-conduction protection

▪ 100% duty cycle operation

▪ Selectable fast or slow current-decay modes

▪ Internal PWM peak current control

▪ High-current gate drive

▪ Motor lead short-to-ground protection

▪ Internal 5 V regulator

▪ Brake input

▪ PWM torque-control input

▪ Fault-diagnostic output

▪ Tachometer output

▪ Thermal shutdown

▪ Undervoltage protection

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 the maximum current limit.

Optionalsynchronousrectificationisincluded.Thisfeaturewill

short out the current path through the power MOSFET reverse

body diodes during the PWM off-cycle current decay.This can

minimize power dissipation in the power MOSFET, eliminate

theneedforexternalpowerclampdiodes,andpotentiallyallow

more economical choices for the MOSFET application.

Packages

The A3932 includes the commutation logic for Hall sensors

configuredfor120degreespacing.PowerMOSFETprotection

features include bootstrap capacitor charging current monitor,

undervoltagemonitor,motor-leadshort-to-ground,andthermal

shutdown.
