DRV8818 - Stepper Motor Controller

General Description

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.

Key Features

  • Pulse Width Modulation (PWM) Microstepping Motor Driver.
  • Built-In Microstepping Indexer.
  • Up to 8 Microsteps/Step.
  • Step and Direction Control.
  • Programmable Mixed Decay, Blanking, and Off Time.
  • Up to 2.5A Current Per Winding.
  • Low 0.37Ω (HS + LS) MOSFET RDS(ON) (25°C).
  • 8V to 35V Operating Supply Voltage Range.
  • Pin to Pin Upgrade for DRV8811 With Lower RDS(ON).
  • Thermally-Enhanced Surface Mount Package.
