MAX1493X Evaluation Kit
General Description
Features
● Ease of Use
The MAX1493X evaluation kit (EV kit) demonstrates the
functionality of the MAX1493X 4-channel, unidirectional,
digital isolators in a 16-pin, SOIC surface-mount package.
The functionality and performance of the QSOP versions
(MAX1413x) can be tested indirectly by using this EVkit
populated with any of the equivalent narrow or wide
SOIC (MAX1493x) devices. The functionality and electri-
cal performance of the QSOP versions are identical to
their corresponding SOIC versions. 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 Up to 5kV
Isolation
RMS
(for the Wide-Body SOIC Version)
• Also Evaluates the 2.75KV
RMS
Versions.

MAX1493X Evaluation Kit
Quick Start
Detailed Description of Hardware
(or Software)
The MAX1493X EV kit is powered from two +5V supplies,
as described below.
Required Equipment
● MAX1493X EV kit
● MAX1493X device separated sampled
● Two 5V DC power supplies or USB cables with a
micro-B connector
● Signal/function generator
● Oscilloscope
External Power Supplies
Power on the MAX1493X 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. Both
options have a reverse-current protection diode.
Procedure
The MAX1493X EV kit has everything except the DUT
installed. The user can install the desired flavor of
the MAX1493X family of unidirectional isolators. Once
installed, follow the steps below to verify board operation:
The MAX1493X level-shifts the data and control signals,
transmitting them across the isolation barrier. Each supply
is set independently and can be present over the entire
specified range of the device, regardless of the level or
presence of the other supply.
1) Connect the DC power supplies between the
MAX1493X EV kit’s VDDA/VDDB and GNDA/GNDB
test points.
2) Turn on the DC power supplies and set to 5V, then
enable the power-supply output.
Figure 1 is a simplified schematic showing the connections
for evaluating the MAX1493X in a simple microprocessor
interface. The MAX1493X level-shifts the signals and
transmits them across the isolation barrier.
Note: It is also possible to power the MAX1493X 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. Please ensure that only one type of
supply is used on either side (USB or DC power
supply).
3) Connect any signal to the SMA connectors or test
points and observe the isolated signal on the other
side using an oscilloscope.

Termination
Jumpers
Each input and output has an unpopulated resistor and
capacitor to GND_ to allow terminating based on customer
requirements.
Two jumpers (ENA/ENB) are provided to enable either side
of the isolation barrier. These are active-high signals. To
enable each side, connect to VDDA/VDDB, respectively.
