MM3508C Series

Lithium-Ion Battery 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 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.

Outline

MM3508C series is a double protection IC for 2-3 cell Li batteries.
It detects battery voltage for each cell.The terminal CT is used to control the output voltage of the terminal OV.

For 2 to 3 cells secondary protection
