Datasheet
Simple design with built-in self-controlled cell balance features circuit
Cell Balance LSI of 4 to 6 Series Power
Storage Element Cells for Automotive
BD14000EFV-C
General Description
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
Key Specifications
Input Voltage Range8.0V to 24.0V
Cell Voltage Detection Range2.4V to 3.1V
Cell Voltage Detection Accuracy:③1(Max. at
25°C)
Shunt Switch ON Resistance1(Typ.)
Operating Temp. Range -40°C to +105°C
Package
HTSSOP-B30
W (Typ) x D (Typ) x H (Max)
10.00mm x 7.60mm x 1.00mm
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.
Features
AEC-Q100 qualified(Note1)
All EDLC cell balancer functions are integrated on
a single chip
