The DRV8818 provides an integrated stepper motor driver solution 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.

A simple STEP/DIRECTION interface allows easy interfacing to controller circuits. The mode pins allow for configuration of the motor in full-step, half-step, quarter-step, or eighth-step modes. Decay mode and PWM off time are programmable.

Internal shutdown functions are provided for over current protection, short circuit protection, under-voltage lockout and overtemperature.

The DRV8818 is packaged in a 28-pin HTSSOP package with PowerPAD.
