MAX14713 Evaluation Kit
Evaluates: MAX14713/MAX14714
General Description
The MAX14713 evaluation kit (EV kit) is a fully assembled
and tested circuit board that demonstrates the MAX14713
power path selector. To evaluate the MAX14714, request
a sample from Maxim and replace the MAX14713 with
the MAX14714.

Procedure
1)
2)
The MAX14713 EV kit is fully assembled and tested.
Follow these steps to verify board operation:
Verify that all jumpers are in their default positions.
Connect 3V DC supply to VIO. Turn on the power
supply.
3) Connect one 5V DC supply to IN1. Connect one 5V
DC supply to IN2.
4) Turn on IN1 supply. Verify LED1 is on and OUT is 5V.
5) Turn off IN1 supply. Verify LED1 is off.
6) Turn on IN2 supply. Verify LED1 is on and OUT is 5V.
7) Turn off IN2 supply. Verify LED1 is off.
8) Set IN1 to 4V and IN2 to 3.5V, and turn on both
power supplies. Verify OUT goes to 4V.
9) Increase IN2 to 4.1V. Note that OUT is still 4V.
10) Slowly increase IN2. Verify OUT = IN2 when IN2
reaches ~4.2V.
11) After OUT = IN2. Decrease IN2 to 3.9V. Verify OUT =
IN2 still.
12) Slowly decrease IN2. Verify OUT = IN1(4V) when IN2
reaches ~3.8V.

Detailed Description of Hardware
Output Load
The MAX14713 EV kit is a fully assembled and tested circuit
board demonstrating the MAX14713 power path selector IC
in a 15-bump, surface-mount, wafer-level package (WLP).
The MAX14713 EV kit features an LED to indicate that
input is powered from either channel 1 or 2.
Use JU3, JU5, and JU7 to select output load. See
Table 2
for jumper settings.
