Hi all,
Recently I designed a custom PCB circuit that operates by a push-button on/off controller. I'm using LTC2951-1 controller for that purpose. My circuit is working fine, except when I power it on for the first time after leaving it off for like 5 mins.
What happens is, when I push the button the EN output of the controller goes high for 3ms and then it goes low, and never actually turns on the system. I have to release the button and then press it again, only then normal operation is observed.
After that, I can turn off and turn on the circuit normally. But If I leave it off for 5 mins again, then the strange behavior is observed again.
I have attached the schematics for controller. Please see it attached
Thanks
