I have microcontroller board with me. which requires 5v as power supply. I want my board to run 24x7. I want a circuit which recharges the batteris and switch to battery supply without restarting the board.
My idea was to have 12v / 9v DC adapter connected to this battery circuit, where it will recharge the battery if required and 5v power will be given as output from circuit. this will be used to power the microcontroller board.
optional features in this circuit.
•Microcontroller can monitor the battery status by reading the a pin from the circuit / doing i2c / spi communication with circuit.
•Microcontroller can get an interrupt when power supply gets off and on. To know what is main power source
