Li-Ion Battery Protector

General Description

The RT9541 Series are protection ICs for over-

charge/discharge of rechargeable one-cell Lithium-ion

(Li+) batteries by CMOS process.

The RT9541 Series can detect over-charge/discharge

of Li+ one-cell and excess load current and charge

current, further include a short circuit protector for

preventing large external short circuit current.

Each of these ICs is composed of four voltage

detectors, a reference unit, a hysteresis circuit, and a

bidirectional short circuit protector. Package of SOT-

26 is available.
