TPS24741RGER

Hot Swap Controllers Overview

The TPS24741RGER is a single-channel hot swap and OR controller manufactured by Texas Instruments. It operates within a supply voltage range of 2.5V to 18V and draws a typical supply current of 4.2 mA. The device is housed in a 24-VQFN (4x4 mm) package with exposed pad, designed for surface mount installation. It supports an operating temperature range from -40°C to +125°C. Key programmable features include current limiting, fault timeout, overvoltage protection (OVP), and turn-on voltage settings. The component does not contain an internal switch and requires external MOSFETs for power path control.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting and fault timeout controls for precise power path management
• Provides overvoltage protection and undervoltage lockout to safeguard connected loads
• Supports automatic retry functionality following fault conditions to enhance system availability
• Functions as both a hot swap controller and an OR controller for redundant power architectures

Hot Swap Controllers Applications

• General purpose hot swap protection in industrial equipment
• Redundant power input configurations using OR controller topology
• Peripheral board insertion systems requiring controlled power sequencing
• Telecommunications infrastructure power distribution units

Hot Swap Controllers Procurement Notes

Verify the complete part number including the suffix RGER to ensure correct packaging configuration. Confirm RoHS3 compliance status if required by specific environmental regulations. Check the latest datasheet revision for any updates to electrical characteristics or pin assignments. Ensure the ordering quantity matches the standard reel size specified by the manufacturer to avoid handling discrepancies during assembly.

Hot Swap Controllers Selection Notes

Select this component when external MOSFET switching is preferred for higher efficiency or custom thermal management. Consider the 24-VQFN package dimensions for PCB layout constraints. Evaluate the need for programmable parameters against fixed-parameter alternatives. Verify that the external gate drive capability meets the requirements of the chosen MOSFETs for optimal switching performance.

Hot Swap Controllers Part Context

This device belongs to the TPS2474x family of hot swap controllers from Texas Instruments. It shares functional similarities with other members in the series but offers specific parameter configurations. The family is designed for robust power management in demanding environments. It complements TI's broader portfolio of power switches and eFuse solutions.

Hot Swap Controllers Replacement Considerations

Consult the official TPS2474x datasheet for direct cross-reference information. Verify pin compatibility and electrical specifications before substituting with similar hot swap controllers. Ensure alternative components support the same 24-VQFN package or require adapter modifications.
