Preliminary
RT9545
Li-Ion Battery Protector
General Description
Features
The RT9545 Series are protection ICs for over-charge/ discharge of rechargeable one-cell Lithium-ion (Li+) batteries by CMOS process.
The RT9545 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-23-6 is available.
