Product Overview

This H-Bridge driver incorporates a Back-EMF measurement circuit that allows you to determine motor speed without an encoder. The bridge is based on the National 18200 H-Bridge chip so it has very low resistance (0.4Ω).  It can handle continuous currents of 3A and bursts of up to 6A.

Features

  • 3 Feedback Modes (Back-EMF, Current Sense and Quadrature)
  • Drives loads up to 27.5V
  • 3A continuous current
  • 6A momentary peak current
  • PWM frequency from 39,000-500,000 Hz
