3 Description

•

Low MOSFET On-Resistance

The DRV8841 provides an integrated dual H-bridge

–

2.5-A Maximum Drive Current at 24 V and

motor driver solution for printers, scanners, and other

automated equipment applications. The device can

–

Combined 400 m

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.

•

8.2-V to 45-V Operating Supply Voltage Range

The output driver block consists of N-channel power

•

Low Current Sleep Mode

MOSFETs configured as H-bridges. The DRV8841 an

Protection Features

–

Overcurrent Protection (OCP)

A low-power sleep mode is provided which shuts

–

Thermal Shutdown (TSD)

down internal circuitry to achieve very low quiescent

current draw. This sleep mode can be set using a

–

Undervoltage Lockout (UVLO)

dedicated nSLEEP pin. Internal protection features

–

Fault Condition Indication Pin (nFAULT)

are provided for overtemperature, overcurrent, and

undervoltage. Fault conditions are indicated by a

nFAULT pin.
