L9369

Overview

The L9369-TR is an automotive integrated circuit designed for electric parking braking systems, housed in a 64-pin LQFP package. It operates within a voltage range of 3.4 V to 40 V and withstands temperatures from -40 °C to +175 °C. The device features two H-bridge driver stages controlling eight external FETs, ten fully differential amplifiers, and ten ADC channels. Communication is handled via a 32-bit SPI interface with CRC support.

Feature Summary

Dual H-bridge driver stages for actuator control
Integrated signal conditioning with differential amplifiers and ADCs
AEC-Q100 qualified for automotive reliability
ISO26262 functional safety concept compliance

Applications

Electric Parking Braking (EPB) systems
Cable-puller system configurations
Motor Gear Unit (MGU) applications

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm that the component meets AEC-Q100 qualification standards for your target automotive application. Ensure the LQFP-64 footprint aligns with your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component for dedicated EPB implementations requiring integrated motor drive and sensing capabilities. It is suitable for designs needing precise current monitoring and low-voltage battery operation down to 5.5 V. Consider its specific pinout and SPI interface requirements when integrating with the host microcontroller.
