tm Features TE CH T63H0006B T63H0006B Low supply current : operating current : 3.0uA (TYP.) Standby current : 0.15uA (TYP.) (after detecting over-discharge) www.DataSheet4U.com Li-Ion Battery Protector General Description The T63H0006B 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. After detecting over-charge the VD1 can be reset and the output of Cout becomes high when the VDD voltage is coming down to a level lower than “VREL1”, or when a kind of loading is connected to VDD after a charger is disconnected from the battery pack while the VDD level is in between “VDET1” and “VREL1” in the T63H0006B. The output of Dout pin, the output of over-discharge detector/VD2, switches to low level after internally fixed delay time passed, when discharging voltage crosses the detector threshold from a high value lower than VDET2. After T63H0006B detect the over-discharge voltage, connect a charger to the battery pack, and when the battery supply voltage becomes higher than the ove...
