MAX14727 Evaluation Kit

General Description

Quick Start

The MAX14727 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates the MAX14727

dual-input, bidirectional overvoltage protection with auto-

matic path control device. The EV kit comes with the

MAX14727EWV+ installed. To evaluate the MAX14728/

MAX14731, request a sample from Maxim and replace

the MAX14727 with the MAX14728/MAX14731.

Required Equipment

●

MAX14727 EV kit

Two 15V DC power supply

USB Cable or 5V power supply

Multimeter

Procedure

Features

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

● 3V to 28V Operating Voltage Range

● LEDs Showing INAOK, INBOK

● Proven PCB Layout

1) Connect one power supply to INA and one power

supply to INB.

2) Connect voltmeter to OUT.

3) Connect USB cable to J1 or connect 5V power supply

on TP1 to source VIO.

4) Supply 4.5V to INA. Verify OUT is 4.5V and LED1

is on.

● Fully Assembled and Tested

● EV Kit Board Containing a MAX14727

5) Increase voltage on INA and verify OUT voltage follows

INA voltage. Keep increasing INA voltage, when INA

reaches OVLO threshold 13.75V, OUT voltage goes

down and LED1 is off.

6) Decrease INA voltage, then OUT comes back to be

the same as INA voltage and LED1 is on. Turn off

INA power supply.

7) Supply 4.5V to INB. Verify OUT is 4.5V an LED2

is on.

Ordering Information appears at end of data sheet.

8) Increase voltage on INB and verify OUT voltage

follows INB voltage. Keep increasing INB voltage,

when INB reaches OVLO threshold 13.75V, OUT

voltage goes down and LED2 is off.

9) Decrease INB voltage, then OUT comes back to be

the same as INB voltage and LED2 is on.

10) Set INB voltage to 5V and verify OUT is 5V.

11) Set INA voltage to 3V and turn on INA power supply.

Verify OUT is still 5V.

12) Increase INA voltage. Verify when INA goes to about

4.5V, LED1 is on and OUT voltage is the same as

INA voltage.
