1 Features 3 Description The DRV8846 provides a highly-integrated stepper
motor driver for cameras, printers, projectors, and
other automated equipment applications. The device
has two H-bridges and a microstepping indexer and
is intended to drive a bipolar stepper motor. The
output block of each H-bridge driver consists of Nchannel and P-channel power MOSFETs configured
as full H-bridges to drive the motor windings. The
DRV8846 is capable of driving up to 1.4-A full-scale
output current (with proper heatsinking and TA =
25В°C). 1 PWM Microstepping Motor Driver
