DRV8843PWP

The DRV8843PWP is a dual integrated 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, 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 DRV8843 an supply up to 2.5A peak or 1.75A RMS output current (with proper heat sinking at 24V 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 over-temperature, overcurrent and under-voltage. Fault conditions are indicated by a nFAULT pin.
