MM3513

MITSUMI Voltage Monitor IC for Li-ion Cell Balance Voltage Monitor IC for Li-ion Cell Balance MM3513 Series Outline The MM3513 series are voltage monitor ICs for rechargeable Lithium-ion or Lithium-polymer batteries, using a high voltage CMOS process. Each Lithium-ion or Lithium-polymer battery can be balanced. Each of these ICs is composed of voltage detectors, reference voltage sources, an oscillator, a counter circuit and logical circuits. Features (Unless otherwise specified, Topr=+25°C) (1) High-accuracy detection voltage Detection voltage Hysteresis voltage 3.5V to 4.5V, 5mV steps Accuracy±20mV Accuracy±25mV (Topr=−5 to +60°C) 0V to 0.4V, 50mV steps However,"Detection voltage-Hysteresis voltage<3.5V" is disabled.
