各位高手及大家:
  我用DS2720做一個(gè)充電器的電池保護(hù)芯片,請(qǐng)問(wèn),它的第二腳即PS腳,該怎么接?謝謝大家非常感謝
  它的DASHEET里這樣寫: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
  它寫的我看不太明白,如果用它做保護(hù)器,應(yīng)該不讓它休眠的,因?yàn)樗靡恢惫ぷ鞯?哪么這個(gè)腳究竟是該接高電平還是低電平還是不接??非常感謝各位高手
