TI DRV8834PWPR

The DRV8834 provides a flexible motor driver solution 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 1.5 - A RMS (or DC) continuously, at 25°C with a VM supply of 5 V. The device can support peak currents of up to 2.2 A 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, undervoltage lockout and overtemperature. A low - power sleep mode is also provided. The DRV8834 is packaged in a 24 - pin HTSSOP or VQFN package with PowerPAD (Eco - friendly: RoHS & no Sb/Br).
