The DRV8841 provides an integrated dual H-bridge motor driver solution for printers, scanners, and other automated equipment applications. The device can be used to drive one or two brushed DC motors, a bipolar stepper motor, or other loads. A simple PWM interface allows easy interfacing to controller circuits.

The output driver block consists of N-channel power MOSFETs configured as H-bridges. The DRV8841 an supply up to 2.5-A peak or 1.75-A RMS output current (with proper heat sinking at 24 V and TA = 25°C) per H-bridge.

A low-power sleep mode is provided which shuts down internal circuitry to achieve very low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin. Internal protection features are provided for overtemperature, overcurrent, and undervoltage. Fault conditions are indicated by a nFAULT pin.
