3.7 v battery charger circuit with auto cut off


TL431 & LiIon Battery Codrey Electronics

The TL431 integrated circuit (IC) is a three-terminal adjustable precise shunt voltage regulator. With the use of an external voltage divider, a TL431 can regulate voltages ranging from 2.495 to 36 V, at currents up 100 mA.

We will use this circuit and the cutoff voltage is equal to 2.5V multiplied by 1 plus the ratio between the two resistors of the voltage divider. For example, with 2k and 1K, the cutoff voltage would be 7.5V. When the input is below that voltage, the TL431 will power off the transistor gate so the load is not powered.

This is a simple Li-ion battery charger circuit with an automatic cut-off when fully charged. This circuit will help revive batteries that you think are dead or so old that they can no longer be reused. We made the circuit with commonly used components such as the NE555 timer and TL431 shunt regulator.
