Other Parts Discussed in Thread: TPL5110
I am using TPL5111 in my project (was considering TPL5110 originally)..
What i experience testing this is somehow odd...
I set TPL5111 in ONE SHOT mode and have a 20K resistor installed to set time to aprox 50sec. It seems to work fine and on time. I press the button to trigger the timer DELAY/M_DRV pin and it turns on for 50sec give or take.. if a DONE signal comes in sooner, it turns off and stays off until another manual activation which is i suppose how its supposed to work.
the problem is when setting the chip to work in TIMER mode.
what i get is, it will turn on after powering up and will stay on until it receives a DONE signal. Then it activates again but the time before it does is not the same every time and it varies from 40-47sec
Is this normal to get such variation?
