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.

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).
