主要工程参数(KEI):
a.过充保护:单只电芯的电压偶尔或者持续超过4.325±0.05V(同时仍然能放电),要切断电路停止充电。
Over Charge Prohibition: Shut down the circuitry and stop charge if one of cell’s voltage exceeds more than 4.325±0.05V momentarily or continuously.(Meanwhile, it is able to discharge)
延迟时间:1.5s(Typ.),1.7s(Max.)

b.过充释放:在电芯电压已被检测到充电禁止模式下,如果单只电芯的电压低于4.15V±0.5V,禁止模式将被复位.
Over Charge Release: In case of the cell voltage which has detected charge prohibition mode. If all of cells are less than: 4.15V±0.05V prohibition mode would be reset.
c.过放保护:如单只电芯的电压偶尔或者持续低于2.5V±0.1V(同时仍然能充电),要切断电路停止放电。
Over Discharge Prohibition: Shut down circuitry and stop discharge if one of cell’s voltage becomes less than 2.5V±0.1V momentary or continuously.(Meanwhile, it is able to discharge)
延迟时间:180ms(Typ.), 210ms(Max.)
Delay Time:180ms(Typ.), 210ms(Max.)
d.过放释放:电压达到2.9V±0.1V时需要恢复电压。如电池组没有电压需要恢复时,请连接电源供应.
Over Discharge Release: Recover when the voltage of cells reach above: 2.9V±0.1V. If battery pack is no voltage, please connect the power supply, and the voltage will recover.
e.过流保护:当保护IC检测到电流在(2.1A<I<3.9A,典型值为3.0A)时,会切断电路停止放电。
Excess current protection: When the protection IC detects the current exceeds the specified current(2.1A<I<3.9A ,typ=3.0A,), it shall shut the circuit and stop discharge.
延时时间: 4.48ms(Typ.), 13.5ms(Max.)
Delay time: 4.48ms(Typ.), 13.5ms(Max.)
f.短路保护:当保护IC检测到MOS管上压降大于规定电压(1.2V(Min.), 1.25V(Typ.), 1.3V(Max.)),要切断电路停止放电
Short circuit protection: When protection IC detects the voltage drop on MOS exceeds the
specified voltage (1.2V(Min.), 1.25V(Typ.), 1.3V(Max.)), it shall shut the circuit and shop discharge.
延时时间: 600us(Max.)
Delay time: 600us(Max.)
