Texas Instruments DRV8833C Dual H-Bridge Motor Drivers

Texas Instruments DRV8833C Dual H-Bridge Motor Drivers provide a dual-bridge motor driver solution for toys, printers, and other mechatronic applications. The device has two H-bridges and can drive two DC brushed motors, a bipolar stepper motor, solenoids, or other inductive loads. Each H-bridge output consists of a pair of N-channel and P-channel MOSFETs, with circuitry that regulates the winding current. With proper PCB design, each H-bridge of the DRV8833C can drive up to 700mA RMS (or DC) continuously, at 25°C with a VM supply of 5V. The device can support peak currents of up to 1A per bridge. Current capability is reduced slightly at lower VM voltages. Internal shutdown functions with a fault output pin are provided for overcurrent protection, short-circuit protection, UVLO, and overtemperature. A low-power sleep mode is also provided.
