KTS1682EAY-TR

Overview

The KTS1682EAY-TR is a high-current over-voltage protection switch manufactured by Kinetic Technologies, designed for power distribution applications. It features a single output capable of delivering up to 4 A with a maximum on-resistance of 38 mOhms. The device supports an input voltage range from 2.3 V to 28 V and includes current limiting set at 30 mA. Key timing specifications include a maximum turn-on time of 2 ms and a maximum turn-off time of 100 ns. It operates within a temperature range of -40°C to +85°C and is housed in a WLCSP-12 package.

Feature Summary

• Integrates high-current over-voltage protection with surge handling capabilities
• Provides precise current limiting functionality to safeguard downstream loads
• Features low on-resistance for efficient power distribution
• Supports bidirectional control with fast switching response times

Applications

• High current over-voltage protection switches
• Power distribution systems requiring surge protection
• Load switching applications with input surge requirements

Procurement Notes

Verify the specific suffix EAY against the manufacturer's official datasheet to ensure correct pinout and electrical characteristics. Confirm that the WLCSP-12 package dimensions match your PCB footprint requirements. Check RoHS compliance status through the provided documentation link. Ensure the operating voltage range aligns with your system's power supply specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits that require robust over-voltage protection combined with high current capacity. The 4 A output rating suits applications needing significant load driving capability. Consider the 38 mOhm on-resistance for thermal management calculations. The wide input voltage range allows flexibility in various power supply architectures. Verify compatibility with your system's control logic levels and switching speed requirements.

Part Context

This part belongs to the Power Switch ICs - Power Distribution subcategory under Switch ICs. It is specifically engineered as an over-voltage protection device within Kinetic Technologies' portfolio. The WLCSP-12 packaging indicates a compact surface-mount solution suitable for space-constrained designs. It complements other load switches in the series by offering specialized surge protection features.

Replacement Considerations

KTS1668EAY-TR offers similar overvoltage protection but supports up to 30 V input voltage instead of 28 V. Both parts share the same WLCSP-12 package and 4 A output current rating. Verify if the slight difference in maximum input voltage affects your specific application requirements.
