MM3725/MM3726 Series

1 cell lithium–ion/lithium–polymer battery protection IC

Outline

The MM3725/MM3726 series are protection IC using high voltage

CMOS process for overcharge, overdischarge andovercurrent

protection of the rechargeable Lithium-ion or Lithium-polymer

battery. The overcharge, overdischarge,discharging overcurrent,

charging overcurrent, and short protection of the rechargeable

one-cell Lithium-ion or Lithium-polymer battery can be detected.

Each of these IC composed of four voltage detectors, short

detection circuit, referencevoltage sources, oscillator, counter

circuit and logical circuits.
