One-cell Li-ion/Li-polymer

battery protection IC

EC9526

General Description

The EC9526 series are protection IC using high voltage CMOS process for overcharge, overdischarge and overcurrent

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, reference voltage sources,

oscillator, counter circuit and logical circuits.
