Overview:


     AP6113 is a circuit specially designed for high-precision linear lithium battery chargers, which is very suitable for low-cost, portable chargers

use. It integrates high-precision pre-charging, constant current charging, constant voltage charging, battery status detection, low leakage at the end of charging, and charging status indication

Equal performance in one, can be widely used in EPC, mobile multimedia, handheld devices and other fields.

     AP6113 determines its state of charge by detecting the battery voltage: pre-charge, constant-current charging, and constant-voltage charging. When the battery voltage is less than the threshold voltage

 When V MIN (generally 9V), it is in the pre-charged state, and the battery is charged with a small current. The pre-charged current can be passed through the external power supply.

Resistance to make adjustments. After pre-charging makes the battery voltage reach V MIN, it enters the fast charging state of constant current charging, and the charging current I REG can be

Adjusted by the peripheral resistor R1, the constant current charging makes the battery voltage rise to the constant voltage charging voltage V REG (typically 12.6V). Then

In the constant voltage charging state, the accuracy of the charging voltage is better than ±1%. In this state, the charging current will gradually decrease. When the charging current is less than the threshold

Value I TERM, charging is over. After charging, the battery voltage will always be monitored. When the battery voltage is less than the threshold V RECHG

(Generally V REG -200mV), recharge the battery and enter the next charging cycle.

      AP6113 can also increase the end-of-saturation voltage of the battery by adjusting the peripheral resistance, which can be set to the required voltage point.
