What you need

1What 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: EVALL9963).
