Description

MOTOR CONTROLLER STEPPER HTSSOP-28
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 Nchannel power MOSFETs configured as full Hbridges 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, undervoltage lockout and overtemperature. The DRV8818 is packaged in a 28-pin HTSSOP package with PowerPAD™.
