Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This TI datasheet covers the DRV8803, a quad low-side driver IC available in DW, PWP, and DYZ packages. It serves as a protected driver for unipolar stepper motors, DC motors, relays, and solenoids using a simple parallel interface. Key parameters include an operating supply voltage of 8.2V to 60V, maximum drive currents ranging from 1.5A to 1.9A per channel depending on the package, and integrated inductive clamp diodes for turnoff transient protection. The device features built-in overcurrent, short circuit, undervoltage lockout, and overtemperature fault protection indicated by a dedicated nFAULT pin.
