OPTIREG™| Lite SBC Family
Infineon's Lite System Basis Chips (SBC) combine a power supply, CAN FD, and a charge pump in one device
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 DCDC SBC with a DCDC 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+, DCDC 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.
