描述
The SPSB100GS is a fully integrated automotive power management system IC, specifically designed for highly integrated application processors (e.g. Stellar G and P MCU families), offering low-power mode and high-current capability. The device comes with enhanced system power supply functionality and a CAN-FD physical communication layer (available only on the SPSB100GS version).
It combines three switch-mode power supplies together with two integrated linear voltage regulators. The device further integrates two wake-up inputs and advanced fail-safe functionalities. The device also embeds a Long Duration Timer up to 180 days.
The boost controller is intended to sustain cold cranking pulses, start-stop, and weak battery conditions.
Different combinations make it possible to supply the system microcontroller, the integrated CAN-FD transceiver (only for the SPSB100GS version), and external peripheral loads and sensors in several adjustable voltage and current ranges. The SPSB100GS and the SPSB100GBS Sare delivered out of STMicroelectronics factory with default values (rails, power-up and -down sequences) stored in the USER-NVM space as reported in System Supply Configuration 1, but can be also re-programmed by customers based on different application needs.
The STMicroelectronics standard SPI interface allows for 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).
