MJ3401 Series

1 cell lithium–ion/lithium–polymer battery

protection IC

Outline

MJ3401 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 Lithium-polymer battery can be detected.

It's possible by OTP technology to detect unusual state of a Li-ion

battery with very high accuracy.
