[Outline]
This IC are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable Lithium-ion or Lithium-polymer battery.
The high accuracy overcharge detection of each cell of the rechargeable 1-3-cell Lithium-ion or Lithium-polymer battery is possible. Each of these IC composed of four voltage detectors, reference voltage sources, oscillator, counter circuit and logical circuits.The ultra-small package SSON-6A is used to minimize footprints.
