RT9541 Description

The RT9541 Series are protection ICs for overcharge/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 posed of four voltage detectors, a reference unit, a...
