General Description

The EC9522T is protection IC for over-charge/discharge of rechargeable one-cell Lithium-ion(Li+) excess load current, further include a short circuit protector for preventing large external short circuit current.

Each of these IC is composed of three voltage detectors, a reference unit, a delay circuit, a short circuit protector, and a logic circuit.

When charging voltage crosses the detector threshold from a low value to value higher than VDET1, the output of Cout pin, the output of over-charge detector/VD1, switches to low level, charger’s negative pin level.
