LI-ION BATTERY PROTECTOR
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.
FEATURES
* Low supply current.
* High withstand voltage.
* High accuracy detector threshold.
* Variety of detector threshold.
* Built-in protection circuit.
* Output delay of over-charge.
* Ultra small package: SOT-26
SOT-26
APPLICATIONS
* Over-charge/over-discharge protection for Li+
one-cell pack
* High precision protectors for cell-phones and any
other gadgets using on board Li+ one-cell
battery.
