Evaluation Kit
General Description
Features
● Ease of Use
The MAX14933/MAX14937 evaluation kit (EV kit) is a fully
assembled and tested circuit board that demonstrates the
functionality of the MAX14933/MAX14937 2-channel digi-
tal isolators in a 16-pin, wide-body SOIC surface-mount
package. The EV kit features two independent isolated
power supplies independently adjustable to +5V.
• Easy Powering Through Micro-USB or Test Points
• SMA Connectors to Connect to External Equipment
● Guaranteed 5kV
Isolation
RMS
● Fully Assembled and Tested.

The devices level-shift the data and control signals,
transmitting them across the isolation barrier. Each
supply can be set independently and be present over the
entire specified range of the device, regardless of the
level or presence of the other supply.

signals, transmitting them across the isolation barrier.
Procedure
2
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Connect the DC power supplies between the EV kit’s
VDDA/VDDB and GNDA/GNDB test points.
2) Turn on the DC power supply and set it to 5V, then
enable the power-supply output.
Jumpers
Two jumpers (POWA/POWB) are provided to switch
between powering the EV kit using micro-USB supplies or
jumpers. When the jumpers are connected, the EV kit is
powered from the micro-USB ports. In this case, no external
supply should be connected to VDDA/VDDB.
Note: It is also possible to power the EV kit with
standard USB ports. To do so, connect the micro-
B end of the USB cables into PA/PB on the board.
Connect the A-end of the USB cable into the USB
ports.
Pullups
All inputs and outputs are pulled up to the corresponding

with a 4.7K resistor. The user has the option of adding a
resistor or capacitor to ground, or a series resistor depending
on their particular needs.
Detailed Description of Hardware
(or Software)
The MAX14933/MAX14937 EV kit is a fully assembled
and tested circuit board for evaluating the MAX14933/
MAX14937 2-channel digital isolators in a 16-pin, wide-
body SOIC package. The EV kit is powered from two +5V
supplies, as described below.

Power on the EV kit is derived from two +5V sources.
Connect external supplies to the +5V and GNDA test
points, or connect a micro-B USB cable to the on-board
PA/PB connectors to provide the 5V supply. Both options
have a reverse-current protection diode.
