MC33HB2000FK

Overview

The MC33HB2000FK is a high-performance, single-chip H-bridge motor driver designed for automotive and industrial applications. It integrates four low Rds(on) MOSFETs, gate drivers, charge pump, and comprehensive protection circuits. The device supports input voltages from 5V to 28V with peak tolerance up to 40V. Key features include SPI-based programmability for current limits (5.4A, 7.0A, 8.8A, 10.7A) and slew rates (0.25 V/μs to >16 V/μs). It offers extensive diagnostics via SPI, including short-circuit, open-load, overtemperature, and undervoltage detection.
