TPS24742RGER

Hot Swap Controllers Overview

The TPS24742RGER 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 features a 24-VQFN (4x4) package with exposed pad. The device supports surface-mount installation and functions across an operating temperature range of -40°C to +125°C. Key electrical characteristics include a supply current of 4.2 mA. It integrates programmable features for current limiting, fault timeout, overvoltage protection (OVP), and turn-on voltage. The controller includes UVLO and automatic retry capabilities, designed for general-purpose power management applications.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting, fault timeout, overvoltage protection, and turn-on voltage settings for precise power control.
• Provides automatic retry functionality upon fault clearance to maintain system availability without manual intervention.
• Includes undervoltage lockout (UVLO) to ensure stable operation during power-up and power-down sequences.

Hot Swap Controllers Applications

• General-purpose hot-swap controller
• OR controller for redundant power systems

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix RGER to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component matches the 24-VQFN package dimensions and pinout requirements for your PCB layout. Confirm that the supply voltage range and thermal performance align with your system's operational environment and power budget constraints before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this controller when a single-channel solution with automatic retry is required for hot-swap or ORing applications. It is suitable for systems needing programmable protection thresholds including OVP and current limits. Consider the 24-VQFN package size and the 4.2 mA supply current when evaluating space and power efficiency constraints in the design.

Hot Swap Controllers Part Context

This component belongs to the TPS2474x family of hot-swap and OR controllers from Texas Instruments. The family offers integrated protection features for high-side N-channel MOSFETs. The TPS24742 variant specifically distinguishes itself with automatic retry behavior, whereas other variants may offer latch-off modes. It serves as a key power management IC for protecting loads during insertion and removal.

Hot Swap Controllers Replacement Considerations

The TPS24741RGER is a related part within the same family but differs in fault handling behavior, offering automatic retry instead of latch-off. Verify if the specific fault response mode of the replacement matches the system's recovery requirements. Ensure compatibility with existing gate drive circuits and protection threshold programming components.
