TPS2492PWR

Hot Swap Controllers Overview

The TPS2492PWR is a single-channel hot-swap voltage controller manufactured by Texas Instruments, designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of 9V to 80V and features a TSSOP-14 surface-mount package. The device integrates programmable current limiting, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). It supports an operating temperature range from -40°C to +125°C with a typical supply current of 1 mA. The controller includes power-fail detection and latch-off fault protection mechanisms.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting and fault timeout for precise inrush control
• Provides hardware-based overvoltage and undervoltage lockout protection
• Features latch-off fault protection that requires manual reset or UVLO cycle
• Includes power-fail detection capability for system monitoring

Hot Swap Controllers Applications

• Hot-swap controller for backplane systems
• Peripheral board insertion and removal protection
• General-purpose power distribution monitoring

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration, as availability varies between cut tape, reel, and Digi-Reel formats. Confirm RoHS3 compliance status and moisture sensitivity level requirements against your manufacturing process specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with latch-off fault behavior is required rather than auto-retry functionality. Ensure the external MOSFET selection aligns with the programmable current limit settings and that the input voltage range falls within the 9V to 80V operational window for reliable performance.

Hot Swap Controllers Part Context

This part belongs to the TPS249x family of hot-swap controllers from Texas Instruments. It shares architectural similarities with the TPS2493 but differs in fault response behavior, specifically lacking automatic retry capabilities. It serves as a general-purpose power management IC for protecting downstream loads during board insertion events.

Hot Swap Controllers Replacement Considerations

The TPS2493PWR is a related variant within the same family; however, it features auto-retry instead of latch-off. No other direct public substitute part numbers are confirmed in the provided documentation.
