General Description

The T63H0002A 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
