TPS24750RUVT

Hot Swap Controllers Overview

The TPS24750RUVT is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It integrates a high-side N-channel MOSFET driver and protection circuitry within a VQFN-36 package. The device supports an input supply voltage range from 2.5 V to 18 V and provides a programmable current limit up to 12 A. It operates reliably across an extended temperature range of -40°C to +85°C. Key electrical features include integrated power-fail detection, adjustable soft-start, and precise overcurrent protection mechanisms designed for safe board insertion in live systems.

Hot Swap Controllers Feature Summary

• Integrates intelligent high-side switching with built-in fault protection logic
• Provides programmable current limiting and adjustable soft-start ramp rates
• Includes dedicated power-fail detection output for system monitoring

Hot Swap Controllers Applications

• Hot-pluggable peripheral cards and backplane modules
• Industrial control system I/O boards requiring safe insertion
• Telecommunications equipment power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix RUVT confirms the tape-and-reel packaging format when ordering. Ensure the design accounts for the VQFN-36 thermal pad requirements for adequate heat dissipation during high-current operation. Confirm that the selected external components match the device's voltage ratings and current capabilities as specified in the official datasheet.

Hot Swap Controllers Selection Notes

Select this component for applications requiring integrated hot-swap protection without external discrete MOSFETs. The fixed 12 A limit suits moderate-power loads, while the 18 V maximum rating fits standard 12 V systems. Consider the VQFN-36 footprint constraints and ensure PCB layout supports the required thermal performance for continuous operation.

Hot Swap Controllers Part Context

This part belongs to the TPS2475x family of hot-swap controllers, which are designed for safe insertion and removal of circuits into live backplanes. The TPS24750 variant offers a fixed current limit, distinguishing it from programmable counterparts. It serves as a critical power management IC for protecting downstream electronics from surge currents during board insertion events.

Hot Swap Controllers Replacement Considerations

The TPS24751RUVT is a related model within the same family offering similar functionality but may differ in current limit settings or pin compatibility. Verify pin-to-pin equivalence and parameter alignment before substitution.
