DRV8848 2 A dual H-bridge motor drive with PWM control

Major appliances like refrigerators, freezers, and other mechatronic appliances require an efficient way to drive DC motors, bipolar stepper motors, and other loads. Texas Instrument’s DRV8848 is a dual H-bridge motor drive solution fulfills this need while also providing a simple PWN interface that allows easy interfacing to controller circuits. 

DRV8848 features multiple output blocks, each consisting of N-channel and P-channel power MOSFETs configured as full H-bridges to drive the motor windings, as well as circuitry for regulating the winding current through a fixed off-time chopping scheme. The device includes a high output current per H-bridge of up to 2 A of current at 12 V from each output; arranging these in parallel raises the current to 4 A, assuming of course, there’s adequate heat sinking. It requires 4- to 18-V Operating supply voltage range

Like most of TI’s H-bridge motor drive products, the DRV8848 is protected against UVLO, OCP, short-circuit protection, and overtemperature.
