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.
