OMS240/241系列
Description
The OMS240/OMS241 series is a lithium-ion/lithium polymer rechargeable battery protection IC, using high voltage CMOS process and includes high-accuracy voltage detectors and delay circuit. By detecting an external resistor (High-accuracy), the OMS240/OMS241 Series realizes high-accuracy charging and discharging overcurrent protection with less effect from temperature change and battery voltage change.

Short detection voltage 0.050V-0.5V Accuracy±40mV/100mV
(2) Detection delay times are generated by an internal circuit.
(3) 30V High-withstanding-voltage device is used for charger connection pins.
(4) 0 V battery charge function: “available” or “unavailable”
(5) Standby function. “available” or “unavailable”
