ADP5140 GUI INTRODUCTION

Start the GUI either from Start > Programs > Analog
Devices > ADP5140 or from the shortcut icon on the PC
desktop.
When the ADP5140-EVALZ is powered up and the USB-SDP-
CABLEZ is connected properly to the ADP5140-EVALZ, SDP
appears in the Device Type text box in the GUI Device Info
window (see Figure 4).

voltage adjusting, frequency configuration, or warning and
faulting window settings (see Figure 6).

Mask Tabs
The mask tabs (RST_MASK, FAULT_MASK, INT_MASK,
and TRANSITION MASK) contain all fault handler registers
that enable/disable the multiplexer operation to the RESET pin,
FAULT pin, and STATUS pin if any fault occurs (see Figure 7).
Status Tab and Latch Tabs
The status and latch registers can be read in the STATUS
READ, LATCH READ, and LATCH READ 2 tabs to show the
status of the ADP5140, such as feedback pin (FBx) undervoltage,
regulator overtemperature, or AVDD overvoltage lockout
(OVLO) (see Figure 8).
Refer to the ADP5140 data sheet for more detailed information
on all device registers.
