Part Number:TPL5100
Hello,
I have problem with TPL5100. I'm designing device that needs to be powered on with 16 sec. intervals. I used TPL5100 to accomplish that with an analog switch (TS5A3160 to be exact). I drive analog switch from MOS_DRV. No matter if DONE signal is HIGH or LOW measured time of MOS_DRV LOW signal is just 30ms and then it goes HIGH again. In typical application TPL5100 is driving P channel MOSFET. That can't be correct, because device can be turned on just for 30ms. How do I get TPL5100 to work in correct mode -> TPL5100 waits 16sec and turn on analog switch. After DONE signal is there, TPL5100 should switch off MOSFET and connected load.
Thanks in advance.
