CAN-FD SBC with DC/DC and Highside Switch | E521.21 / E521.23

The CAN SBC family provides beside the CAN interface the main µC power supply. Depending on the product version, this can be a DC/DC buck converter or an LDO regulator with 3.3V or 5V output voltage and load current up to 200mA. In the LDO version an external NMOS transistor allows to share the power dissipation between external transistor and internal LDO.

All supplies are monitored and can signalize a fail event by SPI interface. System failure can activate a fail-safe output signal for limp home support. The CAN SBC family provides SLEEP, STOP, ACTIVE, FAILSAFE modes. The CAN transceiver provides CAN FD communication capability. The device is capable to detect local and remote wake-up events which can be individually enabled via SPI.
