MAX22518 Evaluation Kit

Evaluate: MAX22517‒MAX22519

General Description

Features

The MAX22518 evaluation kit (EV kit) provides a proven

design to evaluate the MAX22517–MAX22519 family of

● Self-Generated Isolated Field-Side Supply V

DDF

● 2 Unidirectional Channels with Input Charge Pumps

(MAX22517 and MAX22518) and Open-Drain

Outputs (MAX22518 and MAX22519)

self-powered, dual-channel, 3.5kV

digital isolators.

RMS

The EV kit allows easy access to both channels through

either terminal blocks or test points. The isolated field-side

supply V

can also be accessed using the test points.

DDF

Components

• 24VAC Short Protection

• ±1kV Line-to-Ground and ±2kV Line-to-Line Surge

Tolerance (1.2/50μs Waveform)

The EV kit includes necessary external components to

demonstrate the device’s surge performance (1.2/50μs)

up to ±1kV between input and field ground (differential),

or up to ±2kV between inputs (common mode).

● Terminal Blocks and Test Points for Easy Connection

The MAX22518 EV kit is designed to support all three

variants in the MAX22517–MAX22519 family. Jumpers

on the logic-side outputs (OUT1L and OUT2L) allow to

connect or disconnect the pullup resistors, depending

on whether U1 has open-drain or push-pull outputs. The

evaluation board comes with the wide-body 8-pin SOIC

package type with 5.5mm creepage and clearance. See

Table 1 for EV kit details.

to 5.5V

● Guaranteed Up to 3.5kV

Isolation for 60s

RMS

● -40°C to +125°C Temperature Range

● Proven PCB Layout

The MAX22518 EV kit (MAX22518EVKIT#) is fully

assembled and tested, and comes populated with the

MAX22518AWA+ (Figure 1). The board also supports the

MAX22517AWA+ and MAX22519AWA+, but requires the

user to replace U1. See Table 1 and Evaluate MAX22517

and MAX22519 on MAX22518EVKIT# section for details.

Ordering Information appears at end of data sheet.

The EV kit is powered from a single power supply on the

logic side, V

, in range from 3V to 5.5V. The field-side

DDL

supply, V

is generated by the device and has a nomi-

DDF,

nal voltage of 3.3V. The logic-side ground (GNDL) and

field-side ground (GNDF) are isolated and can have con-

tinuous working voltage difference up to 445V

. For

RMS

evaluating the electrical parameters of the devices without

any isolation between the two sides, a common ground

can be shared between GNDL and GNDF.

Note: When ordering an EV kit, if the desired device is

not the MAX22518AWA+, request samples of the desired

MAX22517–MAX22519 IC that can be soldered to the PCB.
