产品概述

描述

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.

The boost controller is intended only to sustain cold cranking pulses, start stop and weak battery conditions for a transitory time.

Different combinations enable to supply the system microcontroller, external peripheral loads and sensors in several and adjustable voltage and current ranges. SPSB100 is delivered out of ST factory with default values (rails, power-up and down sequences) stored in USER-NVM space as reported in system supply configuration 1 for SPSB100B and in system supply configuration 2 for SPSB100P, but can be also reprogrammed by customers based on different application needs.

The ST standard SPI interface allows control and diagnosis of the device and enables generic software development.

The device offers a set of features to support applications that need to fulfill functional safety requirements as defined by Automotive Safety Integrity Level (ASIL).
