L9369S-TR

Power Management - Specialized Overview

The L9369S-TR is an automotive-grade integrated circuit designed for electric parking braking applications, specifically targeting cable-puller or Motor Gear Unit (MGU) configurations. It features two H-bridge driver stages capable of driving eight external N-channel power FETs to actuate rear wheel brakes. The device operates within a voltage range of 3.4 V to 32.0 V and supports temperatures from -40°C to 175°C. Packaged in a 64-pin LQFP (10x10 mm) with Tape & Reel delivery, it integrates pre-drivers, differential amplifiers, ADC channels, and diagnostic interfaces.
