MM3855LC1RLE

1cell Li-ion/Li-polymer battery protection IC MM3825 series Outline The MM3825 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.

However, the detection voltage rises by the current consumption of IC when R1 is too large, and please use 1kohm or less for R1. Please use 0.01uF or more for C1 to stabilize the operation.
