Hi
I have a working circuit for my project which runs off a Lithium Polymer battery. The battery has a nominal voltage of 9.9V and the circuit draws up to 2 amps. (It's a heat regulator circuit for a pair of gloves)
I'm looking for guidance on how to make a circuit which will disconnect the heater circuit when the LiPo battery voltage reaches about 9V.
I'm quite happy using a dedicated voltage monitoring chip (MAX8211 or MAX 8212) and a relay to disconnect both the monitoring circuit and heater regulator circuit, however I was wondering if it was possible to use a MOSFET and if so, what components should I use.
Cheers for any advice, tips or even actual circuits!
