STMicroelectronics SPSB100G
The SPSB100G is a fully integrated automotive power management system IC, specifically designed for highly integrated application processors (e.g. The device comes with enhanced system power supply functionality and a CAN-FD physical communication layer (available only on the SPSB100G version). Different combinations make it possible to supply the system microcontroller, the integrated CAN-FD transceiver (only for the SPSB100G version), and external peripheral loads and sensors in several adjustable voltage and current ranges.| Part No. | SPSB100G |
