The MAX14529E EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Verify that a shunt is installed on pins 2-3 of jumper
2) Verify that a shunt is installed on pins 2-3 of jumper
3) Verify that a shunt is not installed on jumper JU3
4) Verify that a shunt is not installed on jumper JU4
5) Set the VBUS power supply to provide 5V and dis-
6) Set the +3V3 power supply to 3.3V and disable the
7) Connect the VBUS power-supply positive terminal
8) Connect the VBUS power-supply ground to the
9) Connect the +3V3 power-supply positive terminal to
10) Connect the +3V3 power-supply ground to the
11) Enable both power supplies.
12) Verify that the OUT PCB pad is at 5V.
13) Verify that the LOUT PCB pad is at 3.3V.
14) Verify that the VOK PCB pad is at 0V.
15) Connect the D- PCB pad to ground, and verify that
16) Disconnect the D- PCB pad from ground, and install
17) Install a shunt on jumper JU4 (D- connected to D+,

18) Verify that the CDET PCB pad is at 0V.
19) Increase the VBUS power-supply output to 6V.

21) Verify that the OUT PCB pad is at 0V.
22) Verify that the LOUT PCB pad is at 0V.
The MAX14529E EV kit contains the MAX14529E, an
overvoltage-protection device with a low dropout (LDO)
regulator, ESD protection, and USB charger detection.
The EV kit operates from the 5V DC available from the
USB VBUS. The EV kit’s logic inputs and outputs can
be pulled up by the input/output voltage (VIO) available
from the application system.
The MAX14529E EV kit features a USB jack and PCB
pads that allow convenient interfacing between the
USB port and the application system. Connect the USB
cable to the USB type-AB mini jack on the MAX14529E
EV kit. Connect the system charger to the OUT and
GND PCB pads. Connect the USB transceiver signals
to the D+ and D- PCB pads, and the USB transceiver
input/output voltage (VIO or VPU) to the VPU PCB pad.
Connect the USB transceiver VCC to the LOUT PCB
pad. Connect the OEN, LEN, VOK, and CDET PCB
pads to the appropriate locations in the system micro-
processor circuit.
The MAX14529E EV kit provides jumper JU1 to enable
or disable the overvoltage-protection function in the
MAX14529E IC, thus preventing damage to the protect-
ed components. Table 1 lists the options to enable or
disable the overvoltage-protection function in the
MAX14529E IC.
