TCKE800NL,RF

Current Regulation/Management Overview

The TCKE800NL,RF is a single-channel hot-swap voltage controller and eFuse IC manufactured by Toshiba Semiconductor and Storage. It operates within an input voltage range of 4.4 V to 18 V and supports a continuous current limit of 5 A. The device features an adjustable source current control mechanism and exhibits an on-resistance (Ron) of 28 mOhm. Designed for surface-mount installation in WSON10B-10 packages, it functions reliably across an operating temperature range from -40 °C to +85 °C.

Current Regulation/Management Feature Summary

• Integrates latch-type protection circuitry for reliable load management
• Provides adjustable source current control for customizable ramp-up timing
• Features low on-resistance to minimize conduction losses during operation

Current Regulation/Management Applications

• Hot-swap insertion in server backplanes
• Power distribution units requiring controlled turn-on
• System board power sequencing applications

Current Regulation/Management Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and functional specifications. Ensure that the ordering information matches the exact package type and thermal requirements of the target design. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring controlled power ramp-up to prevent inrush current issues. The adjustable source current feature allows customization of turn-on time based on downstream capacitance. Verify that the 18 V maximum input rating aligns with the system supply voltage and that the 5 A current limit meets the load requirements without triggering unnecessary fault conditions.

Current Regulation/Management Part Context

This part belongs to the TCKE8 series of hot-swap controllers from Toshiba. These devices are categorized under PMIC power management ICs and are designed to protect loads during insertion events. The series provides integrated solutions for power distribution, replacing discrete MOSFET and control circuits with a compact, single-chip implementation.

Current Regulation/Management Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative hot-swap controllers from other manufacturers only after verifying electrical compatibility, including input voltage ranges, current limits, and package dimensions.
