DESCRIPTION/ORDERING INFORMATION

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. Pins allow 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 PowerPAD™ 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS

and no Sb/Br).
