描述 Description

MJ3542 series are protection IC with integrated MOS-FET for protection of the rechargeable Lithium-ion or Lithium-polymer battery.The overcharge, overdischarge and discharging and charging overcurrent protection of the rechargeable one-cell Lithium-ion or Lithiumpolymer battery can be detected. It's possible by OTP technology to detect unusual state of a Li-ion battery with very high accuracy.

*1 \"CHYS\" is selectable from \"None(0V)\",\"CHYS1\",\"CHYS2\" \"CHYS1\", \"CHYS2\" depend on setting value of Vdet1
*2 \"DHYS\" is selectable from \"None(0V)\",\"DHYS1\",\"DHYS2\",\"DHYS3\" \"DHYS1\", \"DHYS2\", \"DHYS3\" depend on setting value of Vdet2
*3 Please inquire to us about details of the accuracy of Overcurrent detection current,which is varies depending on the setting value.
