Overview

The DRV8845 is a quad full-bridge driver for a wide variety of industrial applications. The device can be used for driving up to two stepper motors or up to four brushed-DC motors. Each full-bridge output is rated up to 1.5 A and 38 V. This driver offers Smart tune decay mode for smooth and quiet operation. Protection features in this driver include thermal shutdown with hysteresis (OTSD), undervoltage lockout (UVLO) and overcurrent protection (OCP).

Features
  • 40-V Abs max voltage
  • Drive up to two stepper motors or up to four brushed-DC motors
  • Protection and diagnostic features
  • EVM firmware field upgradeable without additional hardware
