MC34931: MC34931/S H-Bridge, Brushed DC Motor Driver, 5-36V, 5A, 11kHz/20kHz

The NXP® MC34931 is a monolithic, thermally efficient 36V/5A H-Bridge DC motor driver.

Best thermal efficiency: eSOIC package delivers 2X lower thermal impedance, saving board space and simplifying design
Automatic thermal back-off: Temperature regulated, peak current limiting ensures continuous high availability operation
Real-time load current monitoring: Analog feedback current mirror feature used for motor control or load protection
Design-in simplicity: Integrated H-Bridge with charge pump, control, protection and four MOSFETs
High efficiency: 120 mΩ typical RDS(ON)
5.0V to 36V continuous operation, 42V transient
Operation up to 5A covering a wide range of applications.
3 & 5 V TTL/CMOS compatible
Status flag output reports under-voltage, over-current, and over-temperature fault conditions
Output short-circuit protection (short to VPWR or GND)
Sleep mode with current draw < 20 μA
