Advance Information

5.0 A Throttle Control H-Bridge

33926

The 33926 is a monolithic H-Bridge Power IC 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.

AUTOMOTIVE THROTTLE H-BRIDGE

ACTUATOR/ MOTOR EXCITER

The 33926 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 20 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.

Two independent inputs provide polarity control of two half-bridge

totem-pole outputs. Two independent disable inputs are provided to

force the H-Bridge outputs to tri-state (high-impedance off-state). An

inverted input changes the IN1 and IN2 inputs to LOW = true logic.
