Rohm – BD14000EFV-C: The Industry’s First Monolithic (EDLC) Cell Balancing IC

The BD14000EFV is a self-controlled cell balancer IC with a built-in shunt-type power storage element balancer function that can respond to 4 to 6 cells. This chip can be used for electric double layer capacitors (EDLC) with cell detection voltage range of 2.4V to 3.1V and power storage capacitors which is important for cell balancers with similar electrical characteristics. It has a built-in multiple over-voltage detection function and can also detect abnormal mode such as any characteristic deterioration in cells.
