Hi
My customer is using TPS65381-Q1.
He would like to know how to go RESET mode by external IGN signal at using IGN_PWRL bit.
He uses only Wake-Up by IGN pin.
Could you ansewr the following questions, please?
1.I think TPS65381-Q1 goes RESET mode by a re-cranking on IGN pin at POST_RUN_RST="1".
But, TPS65381-Q1's mode doesn't change in case of "external IGN signal is high all along".
Is this correct?
2.If he doesn't set POST_RUN_RST to "1"(POST_RUN_RST is "0"), TPS65381-Q1 doesn't go RESET mode by a re-cranking on IGN pin.
In other words, In case of POST_RUN_RST="0", TPS64381-Q1 can not go reset mode by external IGN signal at using IGN_PWRL bit
Is this correct?
Best regards
Shimizu
