TJA1145 bus failure detect function inquiries

kevin-mingdong_ — Wed, 07 Nov 2018 02:09:27 GMT

As I see that the transceiver(TJA1043) can detects a bus line short-circuit condition to
VBAT, VCC or GND. However I couldn't find any description about this funciton. I wonder that if TJA1145 has same function.Or is it just a software implement of MCU?

Thank you.

Kevin

TJA1145 doesn't have short-circuit detect function ,but for detail information about Failure Mode and Effect Analysis of short circuit ,you can read AH1309 from page65.

Hi Mr Sun

Thank you for your quick reply. I have read it .

By the way,could you provide detail information about Failure Mode and Effect Analysis of short circuit of TJA1043?
