MAX9937 Evaluation Kit

General Description

Procedure

The MAX9937 evaluation kit (EV kit) is an assembled and

tested PCB used to evaluate the MAX9937 current-sense

amplifier, designed for unidirectional high-side current-

sense applications. The EV kit can be used to dem-

onstrate the applicability of the MAX9937 to withstand

transients, such as load-dump protection, reverse-battery

protection, and filtering for EMI.

The MAX9937 EV kit is fully assembled and tested. Follow

the steps below to verify board operation. Caution: Do

not turn on power supplies until all connections are

completed.

1) Set the input power supply to 12V and connect the

positive terminal to the VBAT PCB pad. Connect the

ground of the power supply to the GND PCB pad.

2) Set the VCC power supply to 5V and connect the

positive terminal to the VCC PCB pad. Connect the

ground of the VCC supply to the GND pad.

Features

● Reverse-Battery and Load-Dump Protection

• -20V to +40V

3) Set the electronic load to sink 2A.

● +4V to +28V Input Common-Mode Range

● +2.7V to +5.5V Supply Range

● Flexible EMI Filtering

4) Connect the electronic load’s positive terminal to the

LOAD pad. Connect the load’s ground to the GND

PCB pad.

● Lead(Pb)-Free and RoHS Compliant

● Fully Assembled and Tested

5) Connect the DVM across the VOUT PCB pad and the

GND pad.

6) Turn on the 5V power supply.

7) Turn on the 12V power supply.

8) Adjust the electronic load current (I

) between 0A

Before beginning, the following equipment is needed:

● 12V, 2A power supply (VBAT)

and 2A and verify that V

according to the following equation:

is proportional to V
