TPS24741RGET

Hot Swap Controllers Overview

The TPS24741RGET 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 supply current of 4.2 mA. The device is housed in a 24-VQFN (4x4) package with exposed pad, suitable for surface mount installation. It functions across an extended 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 supports automatic retry functionality and includes under-voltage lockout (UVLO). It does not contain an internal switch.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting, fault timeout, and overvoltage protection capabilities
• Supports hot swap and OR controller applications with automatic retry functionality
• Features under-voltage lockout (UVLO) for reliable power sequencing

Hot Swap Controllers Applications

• Hot swap controller circuits
• OR controller configurations
• General purpose power management systems

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration, such as tape and reel or cut tape, matches the production requirements. Confirm that the 24-VQFN package dimensions align with the PCB footprint design. Ensure compliance with RoHS3 standards and check moisture sensitivity level (MSL 2) handling procedures during assembly to prevent damage.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with programmable protection thresholds is required. The absence of an internal switch necessitates an external pass element. Consider the 2.5V to 18V input range and the 4.2 mA supply current for power budget calculations. The extended temperature rating makes it suitable for industrial environments requiring robust thermal performance.

Hot Swap Controllers Part Context

This part belongs to the TPS2474x family of hot swap and OR controllers. It shares the same package and basic electrical characteristics with variants like the TPS24740RGET, which differs primarily in fault handling behavior. The TPS24741 specifically offers automatic retry upon fault clearance, distinguishing it from latch-off variants within the same product line.

Hot Swap Controllers Replacement Considerations

TPS24740RGET serves as a public confirmed substitute within the same family, though it utilizes latch-off fault protection instead of automatic retry.
