1 cell lithium–ion/lithium–polymer battery
protection IC
MJ3401 Series
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.
