MC33926

5.0 A throttle control H-bridge

Rev. 16 — 19 February 2020

Data sheet: technical data

1 General description

The 33926 is a SMARTMOS 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. It

meets the stringent requirements of automotive applications and is fully AEC-Q100 grade

1 qualified.

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

undervoltage, overcurrent, and overtemperature 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).
