DRV8847
Description
The DRV8847 device is a dual H-bridge motor driver for industrial applications, home appliances, ePOS printers, and other mechatronic applications. This device can be used for driving two DC motors, a bipolar stepper motor, or other loads such as relays.
Key Features
- Dual H-bridge motor driver - Single or dual-brushed DC motors - One bipolar stepper motor - Solenoid loads
