产品概述
描述
The SPSB100 is a fully integrated power management system IC, especially designed for highly integrated application processors (for example, the Stellar G and P MCU families), offering low -power mode and high current capability. The device comes with enhanced system power supply functionality and CAN FD physical communication layer (only for SPSB100 version).
It combines three switch mode power supply together with one integrated linear regulator, and one reference supply to track one of buck converters. The device integrates further two wake-up inputs and advanced fail-safe functionalities.
The boost controller is intended to sustain cold cranking pulses, start stop and weak battery conditions.
Different combinations enable to supply the system microcontroller, the integrated CAN FD transceiver and external peripheral loads and sensors in several and adjustable voltage and current ranges.
The STMicroelectronics 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 the automotive safety integrity level (ASIL).
