MC33931

5.0 A throttle control H-bridge

Rev. 5.0 — 10 September 2018

Data sheet: technical data

1 General description

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. It meets the stringent requirements of automotive applications and is

fully AEC-Q100 grade 1 qualified.

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 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.

The disable inputs are provided to force the H-bridge outputs to 3-state (high-impedance

OFF state).

2 Features and benefits

• 5.0 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

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

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

• Temperature dependent current limit threshold reduction

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

• Sleep mode with current draw < 50 µA

• AEC-Q100 grade 1 qualified
