MAX22288

Home Bus System (HBS) Compatible

Transceiver

General Description

Benefits and Features

The MAX22288 Home Bus System (HBS) compatible

transceiver can be used in the Home Bus System, where

data and power are passed on a single pair of wires

while minimizing the need for external components.

• Robust Communication with Configurability

• Dynamic Cable Termination Improves Signal

Quality for High-Speed Applications

• Adjustable Slew Rates for Low EMI

• Maximum Data Rate up to 200kbps over 1000m

UTP Cable

• Programmable Receiver Thresholds

• Space Saving

• 4mm x 4mm TQFN package

The MAX22288 provides robust communication by

using dynamic cable termination that improves the

signal quality with longer cables and higher data rates.

The device data outputs AIO/BIO do not load the bus

when the MAX22288 is not powered. The MAX22288

supports passing data with speed up to 200kbps.

• Pin-to-pin Compatible with the MAX22088

• Integrated Protection

The MAX22288 features adjustable receiver thresholds

and driver slew rates that allow the MAX22288 to be

used in a wide variety of systems. Integrated protection

ensures robust communication in harsh industrial

environments.

• IEC 61000-4-2 ±8kV Contact and ±15kV Air-Gap

ESD Protection

• IEC 61000-4-5 ±1kV Transient Surge Protection

with Selected External Components

• -40°C to +125°C Operating Temperature Range

The MAX22288 is pin-to-pin compatible with the

MAX22088, the Home Bus System (HBS) Compatible

Transceiver with Active Inductor. The MAX22288 is

recommended for use in an HBS system where an

external power supply is typically available.

Applications

•

HVAC

Building Controllers

Industrial IoT

The MAX22288 is specified for operation over the -40°C

to +125°C temperature range and is available in a

compact 24-pin 4mm x 4mm TQFN package.
