MAX20331 Evaluation Kit

7) Remove power supply from COM1, connect 1V

General Description

supply on COM2, and verify NC2 is now 1V.

The MAX20331 evaluation kit (EV kit) is a fully assembled

and tested circuit board that demonstrates the MAX20331

high-voltage OVP on audio line device. The EV kit comes

with the MAX20331EWL+ installed. The MAX20331 EV

kit can also be used to evaluate MAX20331A.

8) Increase voltage on COM2. NC2 voltage goes

down to 0V when COM2 voltage reaches about

3.45V.

9) Decrease COM2 voltage. NC2 voltage again fol-

lows COM2 voltage.

Features

● 3.5mm Jack Audio Line Protection

10) Set COM2 voltage to -1V and verify NC2 voltage

is -1V.

● Proven PCB Layout

11) Decrease COM2 voltage and verify NC2 voltage

goes up to 0V when COM2 voltage reaches

about -3.45V.

● Fully Assembled and Tested

EV Kit Contents

● EV kit board containing a MAX20331

Detailed Description

The MAX20331 EV kit is a fully assembled and tested

circuit board demonstrating the MAX20331 audio line

overvoltage protector in a 9-bump wafer-level package

(WLP). The MAX20331 has overvoltage threshold ±3.45V.

Quick Start
