描述 Description

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).

特性 Features

• AEC-Q100 qualified
• 2 configurable (6.5 V, 5 V, 3.3 V) buck converters and peak switching current limit of 3.0 A @ 2.4 MHz or 400 kHz
• 1 configurable (3.3 V, 1.25 V, 1.2 V, 1.1 V, 0.97 V) buck converter and peak switching current limit up to 6.0 A @ 2.4 MHz, with fine tuning configurability around 0.97 (0.94 V to 1.0 V)
• Overcurrent detection and limitation for all bucks
• Integrated soft start on buck stages
• Boost controller 8-9.5 V and peak switching current limit of 4.2 A @ 400 kHz, for sustaining low battery conditions and deep cranking pulse (external power components can be optionally populated)
• One 5 V voltage regulator (120 mA, 2% acc.) for CAN FD supply
• One configurable (5 V or 3.3 V) low drop voltage tracker of all regulators for µC ADC reference supply (10 mA, +/-10 mV)
• One high-side driver for contact monitoring (RON = 55 Ω) with open-load and overcurrent diagnosis
• Dedicated interrupt pin for failure communication
• Device operates in low power mode
• Very low quiescent current in deep-sleep state
• MCU reset generator
• Configurable window watchdog with extended long open window up to 8s and enable/disable function through NVM bit
• 1 CAN-FD transceiver (ISO 11898-2/2016 and SAE J2284 & SAE J2962-2 compliant), fully deactivable via SPI, with local failure and bus failure diagnosis (only for SPSB100 version)
• Device contains temperature warning and protection
• Thermal clusters
• A/D conversion of supply voltages and internal temperature sensors
• STMicroelectronics standard serial peripheral interface (32Bit/ST_SPI) including 4-bit CRC
• 1 fail safe output
• 1 input pin supporting static and dynamic error signal reporting
• Programmable periodic system wake-up feature
• Documentation available for customers that need support when dealing with ASIL requirements as per ISO26262
