MC33932

5.0 A throttle control H-bridge

Rev. 6.0 — 10 September 2018

Data sheet: technical data

1 General description

The 33932 is a monolithic H-bridge power IC in a robust thermally enhanced package.

The 33932 has two independent monolithic H-bridge power ICs in the same package.

They are designed primarily for automotive electronic throttle control, but are 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.

Each H-bridge in the 33932 is able to control inductive loads with currents up to 5.0 A

peak. RMS current capability is subject to the degree of heat sinking 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 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 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 3-state

(high-impedance OFF state).

2 Features and benefits

• 8.0 to 28 V continuous operation (transient operation from 5.0 to 40 V)

• 235 mΩ maximum R_DS(on)@ T_J= 150 °C (each H-bridge MOSFET)

• 3.0 V and 5.0 V TTL / CMOS logic compatible inputs

• Output short-circuit protection (short to VPWR or GND)

• Overcurrent limiting (regulation) via internal constant-off-time PWM

• Temperature dependent current limit threshold reduction

• All inputs have an internal source/sink to define the default (floating input) state
