SLVSAB8G – MAY 2010 – REVISED MARCH 2016 DRV8842 DC Motor Driver IC
1 Features 3 Description The DRV8842 provides an integrated motor driver
solution for printers, scanners, and other automated
equipment applications. The device has one H-bridge
driver, and is intended to drive one DC motor, one
coil of a stepper motor, or other loads. The output
driver block consists of N-channel power MOSFETs
configured as an H-bridge. The DRV8842 can supply
up to 5-A peak or 3.5-A RMS output current (with
proper heatsinking at 24 V and 25В°C). 1 Single H-Bridge Current-Control Motor Driver
8.2-V to 45-V Operating Supply Voltage Range
Five-Bit Winding Current Control Allows Up to 32
