Description

The L99PM72PXP 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.
