H-Bridge, Brushed DC Motor Driver, 5-28 V, 5 A, 11 kHz
The NXP® MC33931 is a monolithic H-Bridge power IC in a robust thermally enhanced package, 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.
- The MC33931 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 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 at frequencies up to 11 kHz
- Processor Expert® component for medium voltage H-Bridge products enables rapid embedded application development.

Features
Key Features
- 8.0 V to 28 V continuous operation (transient operation from 5.0 V to 40 V)
- 235mΩ maximum RDS(ON) @ Tj=150°C (each H-Bridge MOSFET)
- 3.0 V and 5.0 V 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 < 50μ A (each half with inputs floating or set to match default logic states)
