MAX77714 Evaluation Kit
Evaluates: MAX77714 Multichannel
Integrated Power-Management IC
General Description
The MAX77714 evaluation kit (EV kit) is a fully assembled
and tested printed circuit board (PCB) that demonstrates
the highly-integrated MAX77714 PMIC. The device is a
complete power-management IC (PMIC) for mobile devic-
es using System-on-Chip (SOC) applications processors.
The device includes four buck regulators, nine low-drop-
out linear regulators, eight GPIOs, real-time clock (RTC),
backup battery charger, bidirectional reset I/O, interrupt
output, and a system watchdog timer.
The EV kit also includes a MAXQ2000 microcontroller
command module that provides the I
2
C interface to con-
trol power sequence, individual regulator output on/off,
GPIOs, RTC, and setting regulator output voltage.
The MAX77714 evaluation software is provided for easy
evaluation.

Procedure
1)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Install GUI software. Visit
www.maximintegrated.
com/evkitsoftware
to download the latest version
of the EV kit software. Save the EV kit software to a
temporary folder and decompress the ZIP file.
Install all shunts as recommended in
Table 1.
Connect a disabled 3.6V bench power supply
through an ammeter to VIN and GND wire loops.
Set the input current limit of the bench supply to 3A.
Do not enable the output of the bench supply until
prompted.
Enable the output of the 3.6V bench power supply.
Connect a Micro-B USB cable between the EV kit
and the PC and EV kit.
Wait a few seconds for the computer to install the
USB driver. Once the driver is successfully installed,
a Windows pop-up message appears saying that the
“USB Serial Converter” is ready to use.
Open the GUI, and in the upper left corner, select
De-
vice
and then select
Connect
as shown in
Figure 2.
Once connected, a pop-up window appears as shown
in
Figure 3.
Press the
Read and Close
button.
Using an external power supply, apply 1.8V to EN0.
Refer to
Table 2
for default voltages and FPS settings.

This concludes the initial setup procedure. Users are now
encouraged to explore the device and its register settings
with the GUI. During this exploration, be mindful of the
power supply current limit and input current ammeter’s
range so as not to interfere with the operation of the
device under test.
