TPS24772RGER

Hot Swap Controllers Overview

The TPS24772RGER is a single-channel hot swap voltage controller manufactured by Texas Instruments. It operates within an input voltage range of 2.5 V to 18 V and supports a maximum continuous absolute voltage of 30 V. The device utilizes an external N-channel MOSFET for power switching. It features adjustable current limiting with current limiting response during overcurrent events and latch-off fault response. The component is housed in a 24-pin VQFN package (4x4 mm) and is rated for operation between -40°C and +125°C.

Hot Swap Controllers Feature Summary

• Provides precise control for inserting or removing boards from live backplanes without system disruption
• Features adjustable current limit and programmable slew rate to manage inrush current and prevent voltage droop
• Includes comprehensive protection mechanisms such as undervoltage lockout, overvoltage protection, and thermal shutdown

Hot Swap Controllers Applications

• Telecommunications infrastructure equipment requiring safe board insertion
• Industrial automation systems with modular I/O architectures
• Data center server blade management and hot-pluggable peripheral connections

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'RGER' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 24-VQFN footprint matches the design layout. Ensure compliance with RoHS directives and check moisture sensitivity levels for storage and reflow soldering requirements before procurement.

Hot Swap Controllers Selection Notes

Select this component when a latch-off fault response is preferred over auto-retry for critical system protection. Compare against TPS24770 and TPS24771 variants based on the required fault handling strategy. Ensure the external MOSFET selection aligns with the controller's gate drive capabilities and current limit settings for the target application load.

Hot Swap Controllers Part Context

This part belongs to the TPS2477x family of high-performance hot swap controllers designed for robust power management. It shares core architectural similarities with the TPS24770 and TPS24771 but differs primarily in its fault response behavior. The family targets applications demanding reliable power sequencing and protection in dense electronic environments.

Hot Swap Controllers Replacement Considerations

TPS24770RGER serves as a functional alternative if latch-off fault response is acceptable. TPS24771RGER is suitable if auto-retry functionality is required instead of latch-off. Verify pin compatibility and parameter alignment before substitution.
