The DRV887x device family is suitable for many applications that require half-bridge or H-bridge power stage configurations. Common application examples include brushed DC motors, solenoids, and actuators. The device can also drive many common passive loads, such as LEDs, resistive elements, and relays. The following application examples focus on using this device in a bidirectional current control application requiring an H-bridge driver, and in a dual unidirectional current control application requiring two half-bridge drivers.
