Part Number: TCAN1145-Q1
Tool/software:
Hi team，
I would like to ask about the abnormal recovery of undervoltage status.
During the bus test, the power supply voltage dropped from 14.5V to 5.85V. During the process, tcan was set to SLEEP and all messages were stopped. This was normal.
However, when the power supply voltage rose from 4.5V to the normal voltage of 12V, the message sending was not restored. During this process, tcan was set to NORMAL at 5.7V. Debug found that the can status register on the MCU side was set to the bus off state.
The bus off interrupt would keep jumping. At this time, the error status register ESR1=0x2a0036
Please help confirm the cause of this phenomenon. In addition, what is the normal working voltage of TCAN?
