MAX14838 Evalution Kit
General Description
The MAX14838 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX14838 pin-
configurable industrial sensor output driver.
Detailed Description of Hardware
The MAX14838 EV kit is a fully tested circuit board
demonstrating the capabilities of the MAX14838 industrial
binary sensor driver. The EV kit is designed to demonstrate
all of the major features of the device.
The MAX14838 EV kit may also be used to evaluate the
MAX14839.
Configuring the DO Output
The MAX14838 is a pin-configurable binary sensor driver that
can be configured for NPN, PNP, or push-pull operation in a
normally-open or normally-closed configuration. Set the NO
(J2), PP (J3), and NPN (J5) jumpers high or low to configure
the DO output. Table 2 shows the DO configuration settings.
Features
● Operates from a Wide 4.75V to 34V Supply
● Standalone Operation
● Proven PCB Layout
LDO Linear Regulator
● Fully Assembled and Tested
Ordering Information appears at end of data sheet.
The MAX14838 features and intergrated 5V low-dropout
linear regulator (VLDO) to power external loads up to 30mA.
Quick Start
LED Output Drivers (LEDS, LED2)
The MAX14838 EV kit includes two on-board LEDs for
visual feedback.

The LEDS output (LED1) indicates the state of the DO
driver. See Table 2.
24V, 1A Power Supply
Mulimeter or voltmeter
Function/signal generator
Oscilloscope
The LED connected to the LED2 output (LED2) is a
general-pupose LED and can be turned on or off with the
LED2IN input. Connect the J4 jumper high (1-2) to turn
the LED2 output off. Connect the J4 jumper low (1-4) to
turn the LED2 output on.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation before exercising the full
features of the device:
The default connection for the J4 jumper (1-3) connects
the LED2IN input to the FAULT output. In this configuration,
the LED2 output turns on when FAULT goes low due to an
overcurrent or thermal shutdown condition on DO.
1) Verify that all jumpers are in their default positions, as
shown in Table 1.
2) Connect the 24V DC power supply to VCC and GND
test points on the EV kit board.
3) Connect the multimeter to the VLDO and GND test
points on the EV kit board.
4) Turn on the power supply.
5) Verify that the mulitmeter reads 5V on the VLDO pin.
5) Set the function/signal generator to generate a 0-3V
1kHz signal.
5) Remove the J1 jumper.
6) Connect the function/signal generator to the DIN test
point. Connect the oscilloscope to the DO test point.
6) Verify that DO switches as expected.
