Description
General part information
DRV8818 Series
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.
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.
