Infineon ISO1I811TXUMA1 High Side 8, Controller Power Switch IC 48-Pin, TSSOP

This power switch IC is a high-side controller designed for surface-mount applications where controlled power distribution and multiple input signalling are required. It provides a single switched output governed by a parallel interface, suitable for industrial control environments that demand recognised safety standards and operation across a wide temperature range.

• High-side controller with parallel interface for fast load switching
• Supports one output while processing eight distinct inputs for control flexibility
• Power handling up to 800 mW enabling low-power switching tasks
• Supply voltage range covering 6.5V to 9.6V for varied system designs
• Operates between -40 °C and 85 °C for extended environmental resilience
• 48-pin TSSOP surface package facilitating compact PCB assembly

• Suitable for industrial automation requiring galvanic isolation compliance
• Ideal for control modules with multiple sensor or command inputs
• Used for low-power actuator switching in machinery control panels
• Can be used for interface boards leveraging parallel command structures
• Appropriate for surface-mount production in space-constrained assemblies

The device conforms to UL1577 and EN60664-1 standards, providing recognised isolation and clearance/creepage criteria for safe interfacing.

It arrives in a TSSOP package with surface-mount leads and 48 pins, enabling dense component placement and standard solder reflow processes.

It accepts eight separate input lines and provides a single controlled high-side output for switching loads.

It meets IEC 61131-2 requirements, aligning with specifications commonly applied to programmable controller interfaces.
