LI-ION BATTERY PROTECTOR
SC451XX
DESCRIPTION
The SC451XX series are protection ICs for over-charge
/discharge of rechargeable one-cell Lithium-ion (Li+) batteries
by CMOS process.
The SC451XX 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.
