ISO1I813TXUMA1

Overview

The ISO1I813TXUMA1 is an eight-channel digital isolator from Infineon Technologies, designed for isolated digital input power driver applications. It features galvanic isolation with a rated insulation voltage of 500 Vrms and bidirectional signal polarity. The device operates within a supply voltage range of 2.85 V to 5.5 V and draws a typical operating supply current of 5 mA. It utilizes a TSSOP-48 surface-mount package and supports industrial temperature ranges from -40°C to +85°C. The component exhibits a propagation delay of 8 µs and complies with IEC61131-2 Type 1/2/3 characteristics for digital inputs.

Feature Summary

• Provides galvanic isolation for eight independent digital input channels
• Supports bidirectional signal transmission for flexible interface configurations
• Complies with IEC61131-2 Type 1/2/3 standards for digital input processing
• Operates reliably across extended industrial temperature environments

Applications

• Data center infrastructure interfaces
• Cloud computing system connections
• Internet of Things (IoT) device gateways
• Cybersecurity hardware implementations

Procurement Notes

Verify the complete part number including the XUMA1 suffix to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance and halogen-free status requirements against specific project constraints. Check moisture sensitivity level handling procedures during storage and assembly. Validate that the TSSOP-48 footprint matches the target PCB design guidelines. Ensure supplier documentation aligns with the official Infineon datasheet revision history.

Selection Notes

Select this component when eight isolated digital inputs are required with bidirectional capability. Consider the 500 Vrms insulation rating for safety-critical separation needs. Evaluate the 8 µs propagation delay against system timing requirements. Compare power consumption at 5 mA against low-power alternatives if battery operation is critical. Verify compatibility with IEC61131-2 standard digital input circuits in industrial control environments.

Part Context

This device belongs to Infineon's ISO1I family of isolated industrial interface products. It complements other channel variants like the ISO1I811T, which offers unidirectional functionality. The series targets high-reliability applications requiring robust galvanic separation between control and power domains. It integrates into broader system designs alongside power management and communication ICs.

Replacement Considerations

The ISO1I811TXUMA1 serves as a related variant but provides unidirectional isolation instead of bidirectional support. Verify channel count and signal direction requirements before substitution. Both devices share similar packaging and electrical supply characteristics.
