[Outline]
MM3508B series is a double protection IC for 2 to 4 serial cells lithium-ion / lithium-polymer rechargable secondary battery.It detects battery voltage for each cell.
Each of these IC composed of four voltage detectors, reference voltage sources, oscillator, counter circuit and logical circuits.

[Features] (Unless otherwise specified, Topr=+25℃)

1. Range and accuracy of overcharge detection/hysteresis voltage
