MOSFET Low Dropout Charger Circuit

This circuit is design circuit for low drop out charger using a MOSFET as the pass element, but this circuit does not include current limiting. This is the figure of the circuit.


This circuit is a simple design. This circuit uses Q3 and a Schottky diode to isolate the battery from the charging circuitry when the input voltage is removed, to prevent the battery from discharging. Q2 should be a high current (0.2Ω) FET, while Q3 can be a low current (2Ω) device.
