General Description
The CAN/LIN SBC family with DC/DC voltage reg-
ulator provides beside the CAN and LIN tran-
ceivers the main µC power supply with a high effi-
ciency DC/DC converter. An additional linear regu-
lator can be used independently as peripheral sup-
ply. All supplies are monitored and can signalize a
fail event by SPI interface. The main DC/DC sup-
ply monitor can generate a µC reset. System fail-
ure can activate a fail-safe output signal for limp
home support.
The CAN/LIN SBC family provides SLEEP, STOP,
ACTIVE and FAILSAFE states.
The device is capable of detecting local and
remote wake-up events which can be individually
enabled via SPI.
