Product Overview BD14000EFV-C |
| BD14000EFV is a LSI IC designed as a self-controlled cell balancer. It has a built-in shunt-type power storage element balancer function that can respond to 4 to 6 cells. All the functions necessary in a cell balancer are built-in making power storage element cell balancing possible only in this LSI. 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. Also, application-dependent operation can be set since enable control is possible. Small Reel (250pcs) is available.→BD14000EFV-CH2. |
 |
