Description

The SPSB100 is a fully integrated automotive power management system IC,

especially designed for highly integrated application processors (for example,

Stellar G and P MCU families), offering low power mode and high current capability:

the device comes with enhanced system power supply functionality.

It combines a 3-switch mode power supply together with two integrated linear voltage

regulators. The device integrates a further 2 wake-up inputs and advanced fail-safe

functionalities.
