Technical Data

5.0 A Throttle Control H-bridge

33931

The 33931 is a monolithic H-Bridge Power IC in a robust thermally

enhanced package. It is designed primarily for automotive electronic

throttle control, but is applicable to any low voltage DC servo motor

control application within the current and voltage limits stated in this

specification.

THROTTLE CONTROL H-BRIDGE

The 33931 H-Bridge is able to control inductive loads with currents

up to 5.0 A peak. RMS current capability is subject to the degree of

heatsinking provided to the device package. Internal peak-current

limiting (regulation) is activated at load currents above 6.5 A ±1.5 A.

Output loads can be pulse-width modulated (PWM-ed) at frequencies

up to 11 kHz. A load current feedback feature provides a proportional

(0.24% of the load current) current output suitable for monitoring by a

microcontroller’s A/D input. A Status flag output reports under-voltage,

over-current, and over-temperature fault conditions.

HEAT SINK

Two independent inputs provide polarity control of two half-bridge

totem-pole outputs. The disable inputs are provided to force the H-

bridge outputs to tri-state (high-impedance off-state).
