This document introduces the MC33976 single chip integrated circuit, including its main characteristics and functions.
The MC33976 is a single‑packaged, SPI‑controlled dual step‑motor gauge driver IC. It integrates four dual‑output H‑Bridge drivers and control logic to drive two‑phase instrumentation step motors, offering up to 4096 steady‑state pointer positions and a maximum pointer sweep of 340°.
The document provides detailed pin definitions, ordering information, maximum and static electrical characteristics, dynamic timing parameters, and revision history for designers implementing the device in automotive instrumentation and other applications.
