描述 Description

The ET9513A is a cost-effective, fully integrated single-cell Li-Ion battery charger. The charger uses a
CC/CV charge profile required by Li-Ion battery. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, typically 6.9V, to prevent excessive power dissipation.. The charge current and the end-of-charge (EOC) current are programmable with external resistors. When the charge current reduces to the programmable EOC current level during the CV charge phase, an EOC indication is provided by the CHGSB pin, which is an open-drain output.
 Two indication pins (PGB and CHGSB) allow simple interface to a microprocessor or LEDs. When no
adapter is attached or when disabled, the charger draws less than 10uA leakage current from the battery.
