Voltage detector, LiFe, ESP8266 reset
Posted: Mon Nov 07, 2016 7:04 amhello
My ESP module is going from LiFe battery, I want to build battery protect circuit which cut on/off the current trace when the battery voltage is low (~2.7V)/high.
I developed two versions:
1. in picture 1.png the TC54V voltage detector IC turns on/off a FET when the voltage is low/high, this cuts the battery GND pin
2. at second version (2.png) there is a paralell capacitor with reset pin in purpuse delayed reset
I want to ask, which version is more correct, more reliable? Thank you!
