Lite SBC 系列
Infineon’s Lite System Basis Chips combine power supply, CAN FD and a charge pump in one device
Lite System Basis Chip family supports CAN Flexible Data-Rate (FD) and Partial Networking (PN)
Infineon’s Lite System Basis Chip (SBC) family offers high integration and high performance with optimized system cost for various automotive applications. The Lite SBCs family offers two variants: Lite LDO SBC with a low-dropout voltage regulator of 150mA and the Lite DC-DC SBC with a DC-DC buck converter up to 500mA. Both variants are available as 5V or 3.3V output voltage option for microcontrollers, network transceivers, sensors and other peripherals’ power supply.
They feature an auxiliary 5V integrated low-drop voltage regulator with up to 100mA. The communication interface incorporates one CAN transceiver with Flexible Data-Rate performance up to 5Mbit/s according to ISO 11898-2:2016 (including Partial Networking option). The devices include diagnostic and supervision features, supporting ECU functional safety concepts like under-voltage monitoring, window watchdog with reset, fail-safe operating mode and fail-safe outputs.
The entire Lite SBC family is hardware compatible, and is also software compatible with the Mid-Range+, DC-DC and Multi-CAN Power SBC families (TLE926x & TLE927x). All Infineon SBCs are qualified according to AEC-Q100 and are designed to withstand the severe conditions of automotive applications.

Our highly integrated System-on-Chip solutions have various substantial benefits through advanced diagnosis features and minimized number of components.
Space saving: 80% PCB space saving enabled by a leaded TSDSO package with 8.65mm x 6mm footprint
Energy saving: Offers intelligent power saving modes including stop and sleep mode, and the lowest quiescent current
High system reliability: Extensive diagnostics and protections (e.g. fail-safe output, watchdog, fail-safe operating mode) are embedded within the System-on-Chip
Reduced cost: Minimum number of external components reduce BOM cost, part placing and development, purchasing, handling and PCB sizing
Multiple and flexible designs: Platform approach reduces development efforts, increase time to market and reduce design costs
The entire Lite SBC family is pin-to-pin hardware compatible. A platform approach allows faster time-to-market and flexible adaption to the application requirements. It is also software compatible with the Mid-Range+, DC-DC and Multi-CAN Power+ SBC families (TLE926x & TLE927x).
