Toshiba TCKE1401NM 75V 6A eFuse IC

Introduction

The Toshiba TCKE1401NM is a high-voltage electronic fuse, or eFuse, designed to protect power-input circuits from electrical faults and abnormal operating conditions. Supporting input voltages up to 75 V and load currents up to 6 A, it provides an integrated solution for reliable power-path protection in compact electronic systems.

Part Description

The TCKE1401NM is a single-input, single-output eFuse IC housed in a compact VQFN24D package. Unlike a conventional replaceable fuse, it actively monitors operating conditions and can disconnect the output electronically when a fault occurs.

Its protection and control functions include:

• Adjustable overcurrent protection
• Undervoltage protection
• Overvoltage protection
• Short-circuit protection
• Adjustable output slew-rate control
• Thermal shutdown protection
• Fault-response control

With a 75 V maximum input rating, the device is suitable for systems powered from industrial DC rails, automotive-related supply lines, battery packs, and other higher-voltage sources. The adjustable protection behavior allows designers to tailor voltage thresholds, current limits, and turn-on characteristics to the needs of the protected load.

Applications

Potential applications for the TCKE1401NM include:

• 24 V, 36 V, and 48 V industrial power distribution
• 48 V communication and networking equipment
• Battery-powered equipment and battery-management subsystems
• Motor-control power inputs
• Factory automation controllers
• Programmable logic controller input protection
• Point-of-load power protection
• Electronic circuit breakers
• Robotics and automated guided vehicles
• Test and measurement equipment
• Security and surveillance systems
• High-voltage DC accessory power rails

Industries

The TCKE1401NM can be used across several industries, including:

• Industrial automation
• Telecommunications
• Networking and data communications
• Automotive and transportation
• Robotics
• Renewable energy
• Energy storage
• Test and measurement
• Building automation
• Security systems
• Medical and laboratory equipment
• Smart infrastructure

Usage Ideas

1. 48 V Industrial Controller Input Protector
   Add the TCKE1401NM to the input of a PLC, sensor hub, or industrial controller to protect downstream DC/DC converters from short circuits, excessive current, and input voltage transients.

2. Battery Distribution Safety Switch
   Use the eFuse as an electronically controlled protection stage between a battery pack and an electronic load, helping limit fault current and disconnect the load during undervoltage or overheating conditions.

3. Robotic Motor Module Power Guard
   Place the device at the power input of a motor driver or robotics subsystem to manage inrush current through slew-rate control while protecting the supply line from overloads and short-circuit faults.

Conclusion

The Toshiba TCKE1401NM is a compact, high-voltage eFuse IC that combines multiple essential power-protection functions in one device. Its 75 V input capability, 6 A current handling, adjustable protection settings, and thermal safeguards make it a practical choice for demanding industrial, communication, battery-powered, and automation applications where dependable power-path protection is required.
