Monitoring Voltage and Current

Voltage and current monitoring and control are available for the Linear Technology V
power controller U41 via the Linear Technology LTpowerPlay software graphical user
interface and the DC1613A USB-to-PMbus dongle. The onboard Linear Technology U41
LTC3884 power controller listed in
J1 provided for use with the Linear Technology DC1613A USB-to-PMbus dongle. This cable
can be ordered from the Linear Technology website
