L99PM62GXP – Automotive Door Module Internal Fault Chip, Power Management & CAN/LIN Gateway

The L99PM62GXP is a dedicated fault-tolerant power management IC for automotive door modules.
It integrates a high-side driver, a low-side driver, and a CAN/LIN transceiver for body control systems.
This chip is designed to handle internal fault conditions such as short circuits, thermal shutdown, and undervoltage lockout.

It provides two integrated voltage regulators (5V and 3.3V) for powering microcontrollers and sensors.
The device includes programmable watchdog timers and reset generation for system safety monitoring.
Advanced diagnostic features include load current feedback, overcurrent protection, and open-load detection.

Supports low-power standby and sleep modes with very low quiescent current (<50 µA).
Operates across a wide temperature range from -40°C to +150°C for underhood and door environments.
The L99PM62GXP reduces external component count and improves system reliability for door ECUs.

It is ideal for controlling window lifts, mirror fold actuators, door locks, and ambient lighting.
The integrated CAN physical layer enables robust communication with the main body controller.
Use this chip for aftermarket door module repairs or new automotive control unit production.
