UCD90240
SLVSCW0 – FEBRUARY 2015

A SYNC_CLK pin is used as a single-wire time synchronization method. A Master chip constantly drives a 5kHz
clocks to the Slave devices. This offers a precise time base for multiple UCD90240 devices to respond to the
same fault event at the same time. The configuration window is shown in Figure 24. If the system only consists
of a single UCD90240, it is recommended to configure this pin as master clock output. The SYNC_CLK output
can be used as a time base for other purposes if needed.

7.3.14 Voltage Monitoring
UCD90240 monitors up to 24 analog inputs including voltages, current, and temperature. FUSION GUI or a
PMBus host can poll data from UCD90240. FUSION GUI displays monitored rail voltage, current, and
temperature information on its Monitor page. This is especially useful for debugging system-level issues. The
Monitor page interface is shown in Figure 25.
