Battery Charger Circuits
Step 1: Disconnect the battery to be charged. Step 2: Connect the DC power supply to the input. Step 3: Adjust the variable resistor till you get full charge voltage at the output terminal. (For 3.7V Li-ion output voltage will be 4.2V but here we will set it to 4.1V to increase the battery life).
pcb design LTC4002 LiIon Battery Charger... How do I connect the Comp pin? Electrical
This lithium ion battery charger circuit is very similar to the previous, with two differences. First, instead of just using the MOSFET, you also pass the input supply to the load through a diode. By connecting the FET gate to the input power supply and a diode (normally a Schottky) in series, the system load takes power from the input supply.
