Texas Instruments DRV8847 Dual H-Bridge Motor Drivers are for industrial applications, home appliances, ePOS printers, and other mechatronic applications. These devices can be used for driving two DC motors, a bipolar stepper motor, or other loads such as relays. A simple PWM interface allows for an easy interface with the controller. The DRV8847 drivers operate off a single power supply and support a wide input supply range from 2.7 to 18V. The output stage of the driver consists of N-channel power MOSFETs configured as two full H-bridges to drive motor windings or four independent half bridges (in an independent bridge interface). A fixed-off time controls the peak current in the bridge, which can drive a 1A load (2A in parallel mode with proper heat sinking at 25°C TA).
