What you need

1 What you need

• EVAL-L9963-MCU
• USB cable
• Power supply (at least 3 output 0 – 30 V (if possible 60V):
– 1 output to power L9963 (0:60 V)
– 1 output to simulate Cells common mode voltage (0:60 V)
– 1 output to simulate Cell voltage (0:5 V)
• L9963 evaluation GUI STSW-L9963
• NI Labview-runtime 2014
• NI VISA-RUNTIME
Note: Before using the UART/USB bridge FT2232H, the Virtual Com Port (VCP D2XX) driver needs to be installed. It
can be downloaded by the FTDI Chip website.

Board description

Note: 1. EVAL-L9963-MCU can be considered the only stage or the first stage of several stages. The port is the
isolated vertical interface to the next stage (EVAL-L9963-NDS);
2. A second L9963T (optional) may be needed to create a direct loop with the last stage (dual ring access);
3. MCU can be supplied either by USB or by L9001 (PMIC);
4. On board MCU can be bypassed in case a different MCU is needed for the user trials; these pins allow an SPI connection with an external MCU (upon a specific board configuration). Anyway a specific board derivative of EVAL-L9963-MCU has been designed for this purpose (same form factor/layout with MCU not mounted: EVAL- L9963).

8 Preliminary action to open the GUI

Install the following SW on your PC:
• NI Labview-runtime 2014
• NI VISA-RUNTIME
• FTDI driver
– Before using the UART/USB bridge FT2232H, the Virtual Com Port (VCP) driver needs to be installed.
It can be downloaded by the FTDI Chip website.
When all is installed reboot your PC and open STSW-L9963.exe

10 Device Manager appearance

If FTDI Virtual COM PORT (VCP D2XX) driver has been correctly installed, you will find in Windows Device manager a USB serial port under Ports (COM&LPT). Take note of the COM port number (i.e. COM13).

11 GUI usage and setup

11.1 Connection

Steps:
1. Select COM port according to your device manager. The COM led will become green;
2. Press on “get firmware version” button to check the communication with uC and the firmware version. The version should be 1.5;
3. In the “ID assignment” text box write 1 because you are using 1 L9963 then press “Configure IDs Button”, ACK LED will become green. If D13 LED on the board was switched OFF it will be switched ON and will not switch OFF anymore.

11.2 Threshold configuration

Steps:
1. Select Cell overvoltage and undervoltage. i.e. UV 2.8 V and OV 4.250 V;
2. The VCELL_THRESH_UV_OV register will be automatically updated;
3. Select Dev ID 1;
4. Select Write;
5. Press on “Single write/read” button;
6. If communication with L9963 is ok the ACK LED will become green.
