Preliminary

RT9541

Li-Ion Battery Protector

Features

General Description

^zLow supply current

The RT9541 Series are protection ICs for over-

charge/discharge of rechargeable one-cell Lithium-ion

(Li+) batteries by CMOS process.

− Supply current: TYP. 2.0µA

− Standby current (after detecting over-

discharge): Less than 0.2µA

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.

^zHigh accuracy detector threshold

− Over-charge detector: 25mV

− Over-discharge detector: 2.5%

^zBuilt-in protection circuit

− Excess current trip/Short circuit protector in

both charging and discharging direction

^zOutput delay of over-charge adjustable with

an external capacitor: 75mS at 0.01µF

^zUltra small package: SOT26

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.
