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.

SOT-26
