HS2240P.C

Overview

The Semtech HS2240P.C is a HotSwitch protection IC designed to prevent electrical over-stress (EOS) conditions, including lightning, electrostatic discharge (ESD), short circuits, and surge currents. It operates with an input voltage range of 2.7V to 22V and provides a DC output current up to 3.1A. The device features a low on-resistance (R_on) of 40mΩ and a fixed typical current limit of 3.9A. It offers high surge capability compliant with IEC 6100-4-5 standards, supporting 40A at 8/20μs and 2kV at 1.2/50μs. The component includes adjustable overvoltage protection and soft-start functions.

Feature Summary

• Integrated load switch that detects surges and disconnects the load from the power source to protect downstream subsystems
• Compact DFN-14 package design that reduces bill of materials and PCB space requirements compared to traditional fuses
• Adjustable overvoltage protection and soft-start capabilities for customizable system protection

Applications

• Protection against lightning strikes in electrical systems
• Mitigation of electrostatic discharge (ESD) events
• Short circuit protection for downstream loads
• Surge current management in power distribution networks

Procurement Notes

Verify the specific suffix 'C' against official Semtech documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status. Ensure the ordering part number matches the exact datasheet revision required for your design. Confirm package dimensions and pinout compatibility during integration.

Selection Notes

Select this component when a compact solution is needed to replace traditional fuses while providing active load switching and EOS protection. Consider the 22V maximum input voltage and 3.1A output current limits relative to your system's power requirements. Evaluate the need for adjustable overvoltage protection versus fixed threshold options available in other models within the HotSwitch family.

Part Context

The HS2240P belongs to Semtech's HotSwitch family of highly integrated power switches. These devices are engineered to provide robust safety for downstream subsystems by detecting electrical overstress conditions. The series aims to simplify designs by integrating protection logic directly into the power path, reducing the complexity associated with discrete protection components.

Replacement Considerations

Publicly confirmed substitute part numbers for the HS2240P.C are not available in the provided reference data. Verify compatibility with alternative HotSwitch models based on specific electrical parameters such as input voltage range, current limits, and package type.
