INTEGRATED BATTERY CHARGER WITH STANDARD 24 PIN CONNECTOR

摘要

PURPOSE: A 24-PIN integrative battery charger is provided, which can approve power supply without connection of battery by constituting a circuit with a condenser and resistance and MICOM. CONSTITUTION: One side of a resistance(R) is connected to a charger terminal apparatus(CH). The other side of the resistance is connected to a ground terminal(G). One side of a condenser(C) is connected to the charger terminal apparatus. The other side of the condenser is connected to the ground terminal. A transistor is connected to the resistance and the condenser. The transistor performs a switching role. An operational amplifier is connected to the line interlinking the transistor and the charger terminal apparatus. The operational amplifier provides power supply to the resistance only when voltage of more than a fixed level is approved.
