Hi, I am checking that our board is protected form short circuit.
We use TJA1043T(can transceiver).
Question 1.CANH & CANL are shorted during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 2.CANH & GND are shorted during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 3.CANH & Vcc are shorted during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 4.CANH is opened during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 5.CANL & GND are shorted during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 6.CANL & Vcc are shorted during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
Question 7.CANL is opened during communication.
Does TJA1043's protection circuit operate?
Should we protect TJA1043 with software by detecting ERR_N?
If software protection is necessary, how many seconds will it break down in the shortest time?
If the shortest failure time is unknown, please answer other questions.
best regard.
