Dear group:
I am using the Li-Ion battery (7.4V nominal) to power my circuit. I need to monitor the battery volgate and shut down the whole thing when it drops below 6V.
I am using MAX6457 to monitor the voltage. The datasheet is here:
I have trouble selecting values for the resistors R1 and R2. According to the equation on page 8, you should fix R2 and than set R1 = R2 (Vtrip / Vth - 1). I am really confused, what are the values of Vtrip and Vth in my case... not very clear from the datasheet. I know I can select these resistors by trial and error but I have to demostrate devising the correct values according to the datasheet. Thanks in advance.
