TPS24770RGER

Hot Swap Controllers Overview

The TPS24770RGER is a high-performance hot swap controller from Texas Instruments designed for single-channel applications. 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 and features adjustable current limiting with latch-off fault response. It includes an analog current monitor output and operates across a temperature range of -40°C to +125°C in a 24-pin VQFN package.

Hot Swap Controllers Feature Summary

• Provides precise control over power-up sequencing and inrush current using an external N-channel MOSFET.
• Features adjustable current limiting with latch-off protection to safeguard against overcurrent conditions.
• Includes an analog current monitor output for real-time load current sensing and system monitoring.

Hot Swap Controllers Applications

• Telecommunications infrastructure equipment requiring safe board insertion and removal
• Industrial automation systems needing robust power distribution protection
• Data center servers and storage arrays utilizing hot-swappable modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'RGER' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards applicable to your manufacturing region. Ensure the ordering quantity aligns with the manufacturer's standard reel size specifications to avoid partial reel handling issues during production.

Hot Swap Controllers Selection Notes

Select this controller when a latch-off fault response is preferred over auto-retry for critical system protection. It is suitable for designs requiring an analog current monitor signal for diagnostic purposes. Consider the external MOSFET selection carefully to match the device's gate drive capabilities and thermal requirements within the specified operating temperature range.

Hot Swap Controllers Part Context

This component belongs to the TPS2477x family of hot swap controllers, which share similar electrical characteristics and pinouts. The TPS24770 variant specifically distinguishes itself by offering a latch-off fault response, whereas other family members may provide auto-retry functionality. All variants support the same input voltage range and utilize the 24-pin VQFN package for compact integration.

Hot Swap Controllers Replacement Considerations

The TPS24771RGER serves as a functional alternative within the same family but provides auto-retry fault response instead of latch-off. The TPS24772RGET also offers auto-retry functionality and is available in cut-tape or reel formats. Verify that the change in fault response behavior aligns with the system's recovery requirements before substituting.
