DESCRIPTION OF OPERATION(Cont.)

Release of Over Current (or Short Circuit ) Condition

While the protection IC remains in the Over current (or Short circuit ) condition, then if the load is removed or the

impedance between VBAT+ and VBAT- is larger than 500kΩ as well as VCSI<VOI1, M1 will be turned on and the back to

normal condition.

10.

DS Pin

By forcing DS to VDD, the delay time of the overcharge and overdischarge can be reduced to within 50ms;

therefore, testing time of protector circuit board can be reduced. 1.6MΩ pull down resistor is connected between DS

pin and VSS internally. DS pin should be open or connected to VSS in the actual application.
