[Outline]
The ME01 series are protection IC using high voltage CMOS process which has OTP ( One Time Programmable ) ROM built-in for overcharge, overdischarge and overcurrent protection of the rechargeable Lithium-ion or Lithiumpolymer 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, reference voltage sources, oscillator, counter circuit and logical circuits. It's possible by OTP technology to detect unusual state of a Li-ion battery with very high accuracy.
