Hello,
in my project I use TPS4H000-Q1 version B and I drive the led lamp at 12V.
I have to add the test of load disconnection in off state.
Following the indication in data sheet SLVSD73A, at chapter 8.3.6.2.2, I tried to use a pull-up of 18k-39kOhm, but the leds are in on, even if the light is very small.
I tried to increase it but over a specific value, I can not recognize the disconnection in off state.
So there's no solution following the data sheet indication.
My idea is to power the pull-up resistors not at Vs voltage, but less, for example 3.3V, value too much low to power on the leds.
Is it possible to do it? I didn't try because I don't have the application board now.
I await for your opinion.
Best Regards
Federico Battaglin
