MM3513A01NRH MITSUMI Voltage Monitor IC for Li-ion Cell Balance

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.

· 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
