Newbie level 1
Hi everybody,
I try to use the GM862-Quad (datasheet is there **broken link removed**). As the datasheet says I set the output of my uC to an high level, wait 2.5 seconds and then I set it to a low level. Now the GM862 should be on. But it doesn't work. After 5 seconds it shut down.
When I don't set the output low I have an high level on PWRMON but after 5 to 8 seconds this pin goes low for about 200ms and then release. The status LED is blinking one time a second.
What could be the problem??? Or where can I measure something?
Thanks

I measured the reset pin and this is high but after some seconds it goes low. Is this an internal reset???
