mosfet low dropout charger circuit

Posted on Feb 6, 2014

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 preven
