MC34932: MC34932/S H-Bridge, Brushed DC Motor Driver, 5-36 V, 5 A, 11 kHz/20 kHz

Overview

The NXP^® MC34932 consists of two independent, monolithic, thermally efficient 36 V/5 A H-Bridge DC motor drivers in the same package.

Features real-time load current monitoring and automatic thermal back-off ensuring high availability operation in demanding high-current, high-temperature industrial applications
Designed primarily for DC brushed and DC servo motor driver applications within the current and voltage limits stated in this specification
Powered by SMARTMOS^® technology
Processor Expert^® component for medium voltage H-Bridge products enables rapid embedded application development.

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)
5.0 V to 36 V continuous operation, 42 V transient
Dual H-Bridge with operation up to 5 A on each channel 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 (each half with inputs floating or set to match default logic states)
