Kinetic Technologies launches 5A eFuse for power protection

Key Takeaways

  • Kinetic Technologies introduces the KTS1630, a 5A eFuse for enhanced power protection in consumer and industrial systems
  • The device offers adjustable current limit, programmable output slew rate, and fast overcurrent response
  • It supports 5V and 12V systems with a wide 4.5V to 18V operating range
  • The KTS1630 provides integrated overtemperature protection and external reverse-current blocking
  • Two fault-response versions are available: automatic restart (KTS1630A) and latched off (KTS1630B)

Introduction to the KTS1630

Kinetic Technologies has launched the KTS1630, a highly integrated 5A eFuse designed to improve the safety, reliability, and power efficiency of electronic systems. As modern systems require more robust protection due to increasing power density and smaller designs, the KTS1630 helps protect sensitive components from excessive current, short circuits, thermal events, and uncontrolled inrush current.

Features and Benefits

The KTS1630 features an integrated 31mΩ typical power MOSFET, which supports efficient high-current operation across a wide 4.5V to 18V input range. The device's adjustable 1A to 5A current limit enables designers to optimize protection for specific system loads. A programmable output slew rate controls inrush current during startup, preventing input supply droop, connector stress, and unintended system resets.

Comparison of Key Features

Feature KTS1630 Traditional eFuses
Current Limit Adjustable 1A to 5A Fixed protection threshold
Overcurrent Response Fast 100ns typical Slower response times
Operating Range 4.5V to 18V Limited operating ranges
Integrated Power MOSFET 31mΩ typical Higher resistance values
Fault-Response Options Auto-Retry and Latched-Off Limited fault-response options

Fault Response and Protection

The KTS1630 provides fast 100ns typical overcurrent response, helping isolate faults before they can damage downstream circuitry. Integrated overtemperature protection offers an additional level of system protection during abnormal operating conditions. The device also includes a dedicated control output for an external reverse-blocking MOSFET, preventing unwanted reverse current flow in systems with multiple power sources or sensitive shared power rails.

Conclusion

The KTS1630 offers a highly integrated and efficient solution for power protection in consumer and industrial systems. With its adjustable current limit, programmable output slew rate, and fast overcurrent response, the device provides robust protection against overloads, short circuits, and thermal faults.

Bottom Line

The KTS1630 is a reliable and efficient 5A eFuse that enhances the safety and reliability of electronic systems. Its advanced features, including adjustable current limit and fast overcurrent response, make it an ideal solution for designers seeking to optimize system protection and minimize power loss. With its wide operating range and integrated power MOSFET, the KTS1630 is well-suited for a variety of applications, from consumer electronics to industrial systems.
