What is the most efficient design approach to having a PIC sense a battery supply voltage of below 4.5V and put itself into sleep mode?

Several PICs have an internal brownout detection circuit. Some of them have programmable voltages.

Hi Goerge,

Dual slope AD conversion and a threshold value in the code?

Regards, Joerg
