Voltage Monitor IC for Li-ion Cell Balance
MM3513 Series
MITSUMI
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 specifi ed, Topr=+25°C
(1) High-accuracy detection voltage
Detection voltage 3.5V to 4.5V, 5mV steps Accuracy±20mV
Accuracy±25mV (Topr=−5 to +60°C)
Hysteresis voltage 0V to 0.4V, 50mV steps
However,"Detection voltage-Hysteresis voltage
(2) Range of Detection delay time
Detection delay time Selectable from 0.25s , 1.0s , 1.2s , 4.5s
(3) Low current consumption
Normal mode Typ. 1.5µA, Max. 3.0µA
Stand-by mode Max. 0.5µA
(4) Absolute maximum ratings
VDD pin VSS−0.3V to 12V
OUT pin VDD−0.3V to VDD+0.3V
DS pin VSS−0.3V to VDD+0.3V
Storage temperature −55 to +125°C
Operation temperature −40 to +85°C
· Resistors R1 to R5 and capacitors C1 to C5 stabilize a supply voltage ripple. However, if the resistors R1 to
R5 are increased, the detection voltage raises due to through-current in the IC. Therefore, adjust the value to
1k or less. Moreover, the capacitors C1 to C5 should be 0.01µF or more to ensure stable operation.
· For resistors RDC1 to RDC5, the value of bypass current is determined
