DRV8818 Description
The DRV8818 provides an integrated stepper motor driver for printers, scanners, and other automated equipment applications. The device has two H-bridge drivers, as well as microstepping indexer logic to control a stepper motor. The output driver block for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings.
