TPS259261DRCT

Current Regulation/Management Overview

The TPS259261DRCT is a hot-swap voltage controller manufactured by Texas Instruments, designed for single-channel power distribution. It operates within an input voltage range of 4.5 V to 18 V and supports a current limit of 5 A. The device features a low quiescent current of 420 uA and includes power fail detection capabilities. It is housed in a compact VSON-10 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates a high-side N-channel MOSFET with adjustable current limiting for precise load protection.
• Provides power fail detection to signal upstream controllers during fault conditions.
• Supports controlled turn-on slew rates to minimize inrush current during system startup.

Current Regulation/Management Applications

• Server backplane power distribution
• Industrial control systems
• Telecommunications infrastructure

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCT' corresponds to the Cut Tape packaging format when ordering. Confirm that the 18 V maximum input rating aligns with the target bus voltage. Ensure the design accommodates the thermal requirements associated with the VSON-10 package under maximum load conditions. Cross-reference the datasheet for any recent product change notices affecting pinout or electrical characteristics.

Current Regulation/Management Selection Notes

Select this component for applications requiring robust hot-swap protection on 12 V or similar industrial buses. The 5 A current limit suits moderate-power loads where space efficiency is critical. Consider the VSON-10 footprint for PCB layout constraints. Evaluate the need for external components such as gate resistors or timing capacitors based on specific slew rate requirements defined in the official documentation.

Current Regulation/Management Part Context

This part belongs to the TPS25926x series of integrated eFuses and hot-swap controllers. These devices are engineered to replace discrete MOSFETs and complex protection circuits, simplifying board design. The series offers various current limits and voltage ratings to accommodate different power distribution architectures in enterprise and industrial environments.

Current Regulation/Management Replacement Considerations

The TPS259260DRCT is a related variant within the same family. Verify if the specific current limit or internal resistance parameters of the alternative part meet the original design specifications before substitution.
