L9396 Integrated Circuit For Power Management, Power Management Chip With 64-Pin TQFP Package, Multiple Power Modes And Protection

Introduction

The L9396 is a power management integrated circuit (PMIC) designed for automotive applications. It provides multiple power supply outputs for various subsystems, such as microcontrollers, sensors, actuators, and communication modules. It also supports multiple power modes, such as normal, standby, sleep, and wake-up, to optimize the power consumption and performance of the system. Moreover, it features various protection functions, such as overvoltage, undervoltage, overcurrent, short-circuit, and thermal shutdown, to ensure the safety and reliability of the system.
