Detailed features description
– 1 x Thermal Shutdown (Tj > 175 °C = Tsd) if Tj > Tsd: V3V3 is turned off.
There are 5 temperature sensors for OT2 (OUT1..10, OUT13…20, OUT21…28, IGN1…4
are turned off) in different Layout position, they are logically “AND” in case of thermal
shutdown.
ISO9141 interface
– ISO9141 serial interface (K-Line)
CAN transceiver
The CAN bus transceiver allows the connection of the microcontroller, with CAN
controller unit, to a high speed CAN bus with transmission rates up to 1Mbit/s for
exchange of data with other ECUs.
