Description

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

positive supplies for the gate drive and minimize the component

count normally required. The high-side circuitry also employs a

unique FET monitoring circuit that ensures the gate voltages are

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

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.

Optional synchronous rectification is included. This feature will

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

the need for external power clamp diodes, and potentially allow

more economical choices for the MOSFET application.

Packages

38-pin TSSOP (sufﬁx LD)

The A3932 includes the commutation logic for Hall sensors

configured for 120 degree spacing. Power MOSFET protection

features include bootstrap capacitor charging current monitor,

undervoltage monitor, motor-lead short-to-ground, and thermal

shutdown.

The ‘–S–’ part-number suffix indicates an operating temperature

range of -20°C to +85°C. The ‘–LD–’ suffix indicates a 38-lead

TSSOP package. The initial ‘–TR–’ variant suffix indicates

tape and reel packing. The ‘–T’ final variant suffix indicates

lead (Pb) free composition, with 100% matte tin leadframe

plating.
