各位高手及大家:
我用DS2720做一个充电器的电池保护芯片,请问,它的第二脚即PS脚,该怎么接?谢谢大家非常感谢
它的DASHEET里这样写:PS INPUT PIN
The PS pin is internally pulled to VDD through a high-value resistance. PS is continuously monitored for a low-impedance connection to VSS. Connecting PS to VSS wakes up the DS2720 if it was in sleep mode.
If the DS2720 was in active mode, PS has no effect
它写的我看不太明白,如果用它做保护器,应该不让它休眠的,因为它得一直工作的!哪么这个脚究竟是该接高电平还是低电平还是不接??非常感谢各位高手
