MM3563B

MITSUMI 1 to 3cell Li-ion/Li-polymer battery Secondary protection IC 1 to 3cell Li-ion/Li-polymer battery Secondary protection IC MM3563B Series Outline MM3563B series are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable Lithium-ion or Lithium-polymer battery. The high accuracy overcharge detection of each cell of the rechargeable 1~3-cell Lithium-ion or Lithium-polymer battery is possible. Each of these IC composed of four voltage detectors, reference voltage sources, oscillator, counter circuit and logical circuits.The ultrasmall package SSON-6A is used to minimize footprints. Features (Unless otherwise specified, Topr=+25°C) 1.Range and accuracy of overcharge detection/hysteresis voltage Overcharge detection voltage 4.0V to 4.5V, 5mV step Overcharge hysteresis voltage -500mV to -50mV Accuracy±25mV (Topr=0 to +60°C) Accuracy±50mV to 100mV 2.Range of detection delay time Overcharge detection delay time 1ms to (1ms...
