Build with DRV8803 — Datasheet Specs & AI Design Help

00 — Overview

What the DRV8803 does

The DRV8803 is a four-channel low-side driver IC featuring integrated inductive clamp diodes and overcurrent protection. Available in DW, PWP, and DYZ packages, it supports supply voltages from 8.2V to 60V. The device delivers up to 1.9A per channel in the DYZ package or 2A in the PWP package, with a maximum of 800mA to 1A when all channels operate simultaneously. It drives unipolar stepper motors, DC motors, relays, and solenoids. Internal shutdown functions handle overcurrent, short circuit, undervoltage, and overtemperature faults, indicated by a dedicated fault output pin. The parallel interface simplifies control for general low-side switching applications.
