Hi team,
In TCAN334 datasheet, we can find the abs voltage for CANH/CANL is +-14V. The 14V here is that when VCC is powered, right? And if we connect the CANH/L to CAN bus, and don't power VCC, will the IC be damaged ?
In my customer test, they have 2 TCAN334(A & B) on CAN BUS. And device B is powered up after device A. And we found, when device B is attached to the CAN BUS, the BUS voltage will be pulled low to be about 1V for about 500us, then recover. Does that make sense?
