General Description
The T63H0001A series are protection ICs for
over-charge/discharge of rechargeable one-cell
Lithium-ion (Li+) batteries by CMOS process.
The T63H0001A series can detect
over-charge/discharge of Li+ one-cell and
excess load current, further include a short
circuit protector for preventing large external
short circuit current.
Each of these ICs is composed of three voltage
detectors, a reference unit, a hysteresis circuit,
and a short circuit protector. When charging
voltage crosses the detector threshold from a
low value to a 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 pin becomes “H” when the VDD
voltage is coming down to a level lower than
“Vdet1-Vhys1”, or when a charger is
disconnected from the battery pack while the
