DRV8834RGET

DRIVER, MOTOR, DUAL H-BRIDGE, 24VQFN.

The DRV8834RGET is a Low Voltage Stepper with 32-step indexer or dual brushed DC motor driver (indexer or PH/EN ctrl). It is designed for toys, printers, cameras and other mechatronic applications. The device has two H-bridge drivers and is intended to drive a bipolar stepper motor or two DC motors. The output driver block of each H-bridge consists of N-channel power MOSFETs configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current. With proper PCB design, each H-bridge of the DRV8834 can driving up to 1.5A RMS (or DC) continuously, at 25°C with a VM supply of 5V. The device can support peak currents of up to 2.2A 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, under-voltage lockout and over-temperature. A low-power sleep mode is also provided.
