TCKE800NA,RF

Current Regulation/Management Overview

The TCKE800NA,RF is a single-channel hot-swap voltage controller and electronic fuse IC manufactured by Toshiba. It operates within an input voltage range of 4.4V to 18V and supports a continuous output current of 5A. The device features a typical on-resistance (Ron) of 28mΩ. It includes auto-retry functionality for fault recovery and adjustable overcurrent protection (OCP). The component is housed in a WSON10B-10 package and is designed for operation across a temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates auto-retry logic for automatic circuit recovery after fault clearance
• Provides adjustable overcurrent protection thresholds for customized load management
• Features low on-resistance to minimize conduction losses during normal operation

Current Regulation/Management Applications

• Consumer equipment power distribution
• Server backplane protection
• IoT equipment power management
• Storage system input protection

Current Regulation/Management Procurement Notes

Verify the specific suffix and marking code against the official Toshiba datasheet to ensure compatibility with the required voltage clamp and pinout configuration. Confirm that the WSON10B-10 footprint matches the target PCB design. Check for RoHS compliance documentation if environmental regulations apply to the end product. Ensure the operating temperature range meets the system's thermal requirements.

Current Regulation/Management Selection Notes

Select this component when a single-channel eFuse solution is required for 5A loads within a 4.4V to 18V input window. The adjustable OCP allows flexibility for various load profiles. Consider the WSON10B-10 package size for space-constrained designs. Evaluate the need for auto-retry functionality versus latching shutdown based on system reliability requirements.

Current Regulation/Management Part Context

This part belongs to the TCKE8 series of hot-swap controllers from Toshiba. The series offers various voltage clamp options and channel configurations. The TCKE800NA,RF specifically targets general-purpose applications requiring robust input protection and controlled power-up sequencing for sensitive downstream electronics.

Current Regulation/Management Replacement Considerations

Consult Toshiba's official cross-reference documents for verified substitutes. Ensure any replacement maintains the same WSON10B-10 footprint and electrical characteristics, particularly the 5A current rating and 4.4V-18V input range.
