[Outline]
The MM3734 series are voltage monitor ICs for rechargeable lithium-ion or lithium-polymer batteries secondary protection, using a high voltage CMOS process. 1-cell lithium-ion or lithium-polymer battery can be detected overcharge state. Internal circuit is composed of voltage detectors, reference voltage sources, an oscillator, a counter circuit and logical circuits.
