MC33932: H-Bridge Motor Driver, 5-28 V, 5 A, 11 kHz

Overview

The NXP^® MC33932 has two independent monolithic H-Bridge power ICs in a robust thermally enhanced package.

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
Each H-bridge in the MC33932 is able to control inductive loads with currents up to 5.0A 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 6.5A ± 1.5A.
Output loads can be pulse width modulated at frequencies up to 11 kHz
Processor Expert^® component for medium voltage H-Bridge products enables rapid embedded application development.

8.0V to 28V continuous operation (transient operation from 5.0V to 40V)
235mΩ maximum RDS(ON) @ 150°C (each H-Bridge MOSFET)
3.0V and 5.0V TTL / CMOS logic compatible inputs
Over-current limiting (regulation) via internal constant-off-time PWM
Output short-circuit protection (short to VPWR or GND)
Temperature-dependant current-limit threshold reduction
All inputs have an internal source/sink to define the default (floating input) states
Sleep Mode with current draw < 50μA (each half with inputs floating or set to match default logic states)
