RTKA489204DK0000BU
Overview
The RTKA489204DK0000BU is an evaluation kit that
facilitates testing of the
pack analog front-end ICs. The RAA489204 monitors
cell voltage and temperature, and provides 14-bit
digital values, cell balance control, and significant
fault detection. The RAA489204 also contains daisy
chain hardware to provide robust board-to-board
communication.
The evaluation kit operates as a stand-alone monitor
or, combined with additional boards, creates a daisy
chained application. One board operating alone
allows testing of up to 14-cell series-connected Li-ion
battery packs by using a standard USB interface to a
PC. Up to 30 boards cascade (with daisy chain
communication from board-to-board) to test systems
with up to 420 cells.
Specifications
This board is configured and optimized for the
following operating conditions:
▪ V
= 12V to 65V
BAT
▪ Cell voltage -5V to +5V (Note: No cell voltage can
go below pack ground or above 65V.)
▪ External inputs ExT1 to ExT4 = 0V to 2.5V
(external temperature measurement thermistors on
board)
▪ Two GPIO ports to monitor temperature (default) or
general-purpose input or output.
Board Contents
The RTKA489204DK0000BU evaluation kit contains:
▪ RTKA489204DE0000BU RevB evaluation board
▪ MCB_PS4_Z multi-cell power supply test board
▪ RTKA489204MICROZ communications board

  • Page 18 RTKA489204DK0000BU Evaluation Kit Manual uses an Address All device address. The Scan All operation, when using the MCB_PS4_Z boards with the RTKA489204DE0000BU revB boards, produces an Open Wire error on Cell1. This is a result of a voltage drop caused by the MCB_PS4_Z resistor divider, the input filter on the RTKA489204DE0000BU board, the open wire current, and the open wire threshold detection level on VC1.
  • Page 19 RTKA489204DK0000BU Evaluation Kit Manual The polling operation follows the scan command with a read of voltages, faults, and temperatures. The operation processes using read commands for each device to request the contents of the voltage, temperature, and fault registers. When the data is returned, the GUI extracts the information from the buffer to populate the screen and the data collection array.

    Note: This manual operation only performs reads or writes on a single register and does not do error checking, so it is possible to read and write registers that are not defined. Renesas recommends against experimenting in this way, though there are no known problems associated with actions involving undefined registers.

    Renesas recommends selecting fail safe or open mode types for the input capacitors that connect directly to ground. An alternative strategy is to replace each of these capacitors with two devices in series, each with double the value of the single capacitor.

  • Page 44: Questions And Answers

    RTKA489204DK0000BU Evaluation Kit Manual Questions and Answers Q: When the GUI starts up it appears that nothing happens. A: The most common problem encountered when setting up the boards is a connection error. When the GUI powers up correctly and connects to the microcontroller dongle, the green LED on the microcontroller board lights up.

  • Page 45: Errata

    If the voltages are different from these, then there could be a board problem and you should contact your Renesas representative. A2: If both LEDs are off, the board is not powered or the LEDEN jumper is missing. Check that the MCB_PS4_Z board is connected to the Evaluation board and to a power supply and that the switches on the power supply board are set to ON.
