MAX22190ATJ+T

Sensor And Detector Interfaces Overview

The MAX22190ATJ+T is an octal industrial digital input device compliant with IEC 61131-2 standards. It translates eight 24V current-sinking inputs into a serialized SPI-compatible output for 3V to 5.5V logic systems. The component operates directly from a field supply ranging from 7V to 65V and features configurable Type 1, 2, or 3 inputs via external resistors. Integrated diagnostics include wire-break detection, overtemperature monitoring, and CRC error checking. It utilizes a 32-pin TQFN package measuring 5mm x 5mm.

Sensor And Detector Interfaces Feature Summary

• High integration reduces bill of materials count and board space by consolidating eight channels with a serializer.
• Operates directly from the field supply voltage without requiring separate isolated power sources.
• Built-in fault tolerance includes comprehensive diagnostics such as wire-break detection and overtemperature monitors.
• Configurable input current limiting allows adaptation for various sensor types within a single SKU.
