HTSSOP (PWP)-28-62.08 mm² 9.7 x 6.4
The DRV8818 provides an integrated stepper motor driver for printers, scanners, and other automated equipment applications such as textile machines. 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 overcurrent protection, short-circuit protection, undervoltage lockout and overtemperature.
The DRV8818 is packaged in a 28-pin HTSSOP package with PowerPAD™ integrated circuit package.
