ISL94212EVKIT1Z 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
BAT
= 6V to 60V
•V
BAT
daisy chain = 10V to 60V
•VC
n
(for n = 1 to 12) = V(VCn-1) to V(VCn-1) + 5V
•CB
n
(for n = 1 to 9) = V(VCn-1) to V(VCn-1) + 9V
•CB
n
(for n = 10 to 12) = V(VCn) -9V to V(VCn)
• External inputs Ext
1 -4
= 0V to 2.5V
• SPI communications refer to ISL94212
datasheet
•V
POR
(V
BAT
) voltage (rising) typical 5.1V
Key Features
• Supports both stand alone and daisy chained configurations
• Daisy chaining with both connector only or wire jumper
options
•GUI provided export option for generation of detailed
register and/or SPI communications log files.
• USB dongle runs HID firmware for driver-less enumeration
and communications with Windows platforms
• GUI add-in chart generation tool supports real-time
graphing, zoom and export of captured data.
• Software provides checksum requirements associated with
daisy chain communications.
• Kit includes “Battery Emulation” board(s) for cell voltages
generation.

Applications requiring 12 cells or less can operate with a single device as
shown above.
Also the ISL94212 can also operate in a 2 to 14 device configuration (Daisy
Chain). See example to the right.
