Hello Team,
I am using TJA1128 in my control board, which is the primary source 5V for Micro.
There is a failure with TJA, here are the info, could you let me know what could be the problem?
Note: LIN wake up is activated remote, I need to know why there is no 5V at VCC, and Reset is held LOW (may be under voltage at VCC)
PIN | Measured Output in V |
Wake1 | 7.93 |
Wake2 | 7.93 |
BAT | 13.36 |
LIN | 12.68 |
GND | |
VCC | 0 |
TXD/SDI | 0 |
LIN_EN | 0 |
RST | 0 |
RXD | 0 |
WWD | 0 |
Factor to consider,
TJA in my control board were working continuously for 78hrs at ambient temp of 65 deg, it failed at this point of time.
Interesting part is 4 samples failed between 70-90 hrs of continuous running at the same environment with the same issues.
