Hi Expert，
We have a headunit application. The clamping voltage of the TVs tube for the front stage power supply is 39 V, but the main power input for the next chip is 26 V. If a pulse (such as a 7637-related pulse) is coming, it is clamped to 39V after tvs, but it will still exceed 26V of the main power supply of the rear chip. So we see TI's LM74810, which has an overvoltage shutdown capability. The idea is to power off the main power input after an overvoltage. In this way, the chip will not be damaged, but I would like to see if the transient response capability of this LM74810 can be supported, so I would like to take a simulated look. The simulation tool uses LTspice. Because the model of the 7637 waveform is integrated inside.
What does TI pspice do with these models? When we want to open the LTspice model there is an secret code shown on the screen.
Kind Regards
Imelda
