Evaluates: MAX44286

MAX44286 Evaluation Kit

General Description

The MAX44286 evaluation kit (EV kit) provides a proven

design to evaluate the MAX44286 zero-drift, high-side,

current-sense amplifier that offers precision and low

supply current. This EV kit demonstrates the MAX44286

in an ultra-small, 0.78mm x 0.78mm x 0.35mm, 4-bump

wafer-level package (WLP).

The EV kit PCB comes with a MAX44286FAZS+ installed,

which is the 50V/V gain version. Other gain options

are available. Contact the factory for free samples

of the pin-compatible MAX44286TAZS+ (25V/V gain),

MAX44286HAZS+ (100V/V gain), and MAX44286WAZS+

(200V/V gain).

Quick Start

Required Equipment

The following items are required for operation:

• MAX44286 EV kit

• +3.3V, 1.5A DC power supply

• Electronic load capable of sinking 1A

(i.e., HP6060B)

• Two digital voltmeters (DVMs)

Procedure

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

below to verify the board operation.

Caution: Do not

turn on power supply or the electronic load until all

connections are made.

1) Connect the positive terminal of the +3.3V supply to

the VBATT PCB pad and the negative terminal of the

supply to the GND PCB pad closest to the VBATT PCB

pad.

2) Set the electronic load to 1A.

3) Connect the electronic load’s positive terminal to

the LOAD PCB pad and the negative terminal to the

nearest GND PCB pad on the EV kit.

4) Connect the first voltmeter across the RS+ and RS-

test points.

5) Connect the second voltmeter across VOUT and the

nearest GND PCB pad on the EV kit.

6) Enable the power supply.

7) Enable the electronic load.

8) Verify that the first DVM displays 60mV and the

second DVM displays 3.0V.
