Hi Ti,
I did a design with the Nano Power Timer TPL5110. The device works as expected but I am facing one issue which is not mentioned in the datasheet. For my circuit and application i need to hold M-DRV high during POR and after. Only when i want to activate the timer which is not necessary all time ill switch M_DRV with a 2:1 Mux to the Rtimer resistor.
My issue is that if i power up TLP5110 with above condiiton the current draw is about 170uA. Only if I start the first cycle it goes down to about 55nA. In the second cycle when I have same condition as on POR but not running trough POR the current is only 3uA. Is there any way to avoid the 170uA during POR with M_DRV kept high (which is in my case 3,3V by the way)?
Hi Noel, thanks for your effort. We build a circuit arround to bypass this issue. It works fine now.
