TPS2492PW

Hot Swap Controllers Overview

The TPS2492PW is a single-channel hot swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 9 V to 80 V and features a programmable current limit. The device is housed in a 14-TSSOP surface-mount package with a width of 4.40 mm. It supports an operating temperature range from -40°C to +125°C and draws a typical supply current of 1 mA. Key protection features include power fail detection, overvoltage protection (OVP), undervoltage lockout (UVLO), and fault timeout capabilities.

Hot Swap Controllers Feature Summary

• Provides intelligent control for high-side N-channel MOSFETs during insertion and removal events
• Features programmable current limiting and fault timeout settings for customized protection
• Includes built-in overvoltage and undervoltage lockout mechanisms for input monitoring

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe board insertion
• Industrial systems needing controlled power sequencing
• Computing infrastructure utilizing hot-pluggable modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-14 package variant when sourcing. Ensure compatibility with external N-channel MOSFET selection based on the required current limits. Confirm RoHS compliance status matches project requirements. Check for any recent product change notices regarding pinout or electrical specifications before finalizing designs.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise control of inrush current and fault handling without an internal switch. Compare against the TPS2493 series if automatic retry functionality after a fault event is preferred over the latching behavior of the TPS2492. Ensure the external MOSFET Rds(on) and gate drive characteristics align with the controller's output capabilities.

Hot Swap Controllers Part Context

This part belongs to the TPS249x family of hot swap controllers designed for managing power distribution in modular systems. It serves as a critical interface between the main power bus and peripheral cards, ensuring that connection transients do not disrupt system operation. The family offers various configurations to suit different channel counts and retry behaviors.

Hot Swap Controllers Replacement Considerations

The TPS2493PWR is a functional alternative within the same family, distinguished primarily by its support for automatic retry modes rather than latching faults. Verify that the application logic can tolerate the different fault response behavior before substituting.
