Evaluation Kit User Guide
Description
The ISL94212EVKIT1Z is a kit that facilitates use of the
ISL94212
BMS device. The ISL94212 monitors cell voltage and
temperature. It converts the cell voltages and temperatures to
14-bit digital values, provides cell balance control, It provides
significant fault detection. The ISL94212 can operate in a single
device configuration, or multiple kits can be cascaded using a
built-in daisy chain connection. The daisy chain hardware
provides robust, redundant board-to- board communications.
Specifications
This board has been configured and optimized for the following
operating conditions:
• V
= 6V to 60V
BAT
• V
daisy chain = 10V to 60V
BAT
• VC
(for n = 1 to 12) = V(VCn-1) to V(VCn-1) + 5V
n
• CB
(for n = 1 to 9) = V(VCn-1) to V(VCn-1) + 9V
n
• CB
(for n = 10 to 12) = V(VCn) -9V to V(VCn)
n
• External inputs Ext
