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
