L99PM72GXP中文资料高级电源管理系统IC，具有嵌入式LIN和高速CAN收发器，支持CAN局部网络数据手册ST规格书

描述 Description

The L99PM72GXP is a power management system IC providing electronic control units with enhanced system power supply functionality including various standby modes as well as LIN and HS CAN physical communication layers. It contains two low drop voltage regulators to supply the system microcontroller and external peripheral loads such as sensors and provides enhanced system standby functionality with programmable local and remote wake up capability.

In addition, five high-side drivers, two low-side drivers and two operational amplifiers increase the system integration level.

The ST standard SPI Interface (3.0) allows control and diagnosis of the device and enables generic software development.
