**Refer to the MAX5970 IC data sheet for adjusting the circuit breaker threshold range.
The MAX5970 EV kit user interface (Figure 1) is easy to
operate; use the mouse, or press the Tab key to navigate
with the arrow keys. Each of the buttons correspond to
bits in the command and configuration bytes. By click-
ing on them, the correct I²C-compatible write opera-
tion is generated to update the internal registers of the
MAX5970.
Use the Device Address combo box to select the
MAX5970 I²C address. Checking the Silence I2C
Activity checkbox stops activity between the microcon-
troller and the MAX5970 when the software is idle; other-
wise, the software continuously reads the device's status
and data registers to check that the device is working
properly. These functions create activity on the I²C bus.
Use the Read All Registers button to perform a read
of all of the MAX5970 registers and update the GUI
with each register’s data. The status bar located at the
bottom of the GUI displays the status of the registers
accessed, and the data received or sent.

The EV kit software Configuration tab sheet (Figure 1)
displays the Grouping (MODE), Fault Management
(RETRY), Critical Fault Protection (PROT), and
Polarity (POL) general settings at the top, while group-
ing channel-specific settings below. See Table 2 for GUI
control details for each channel. Check the Deglitch
checkboxes located to the right of the OV Critical, OV
Warning, UV Warning, UV Critical, and OC Warning
input controls to enable the deglitch feature for those
settings.
The EV kit software Control / Status tab sheet (Figure 2)
displays the status of each channel, including the volt-
age and current measurements in decimal format. Each
channel can be enabled, regardless of the input voltage,
by configuring the software’s EN1_ and EN2_ combo
boxes, or checking the Force-ON Keys Enable and
Force-ON checkboxes. Check the corresponding Reset
or Hold checkbox to reset or hold the maximum and
minimum voltage measurements and the maximum and
minimum current measurements. Press the Clear Alert
button to clear the alert bit and output signal.
