Hi
Am designing a small project using a single AA 1.5V alkaline battery boosted to 3.3V to power a 18F1220. I would like to have a way to detect a low battery situation which it reaches around 1.25V or lower (not obsessed with accuracy).
What is the best way to achieve this? One way I read involves the use of an IC (eg TSM9118 or STM1601) but detecting single battery low voltage at 1.25V seems to be outside their range.
Am looking for a design involving the least parts and cost involved.
Thanks!
