TPS2482PWR

Hot Swap Controllers Overview

The TPS2482PWR is a single-channel hot swap controller from Texas Instruments designed for positive voltage rails up to 36 V. It integrates an N-channel MOSFET driver with programmable current limiting and precise power monitoring capabilities via an I2C-compatible interface. The device supports input under-voltage lockout (UVLO) with hysteresis and features a remote enable pin for system control. Operating within a temperature range of -40°C to +125°C, it utilizes a TSSOP-20 package. Key electrical specifications include a minimum supply voltage of 9 V, maximum supply voltage of 36 V, and a typical operating supply current of 1 mA.

Hot Swap Controllers Feature Summary

• Integrates precision digital power monitoring accessible through an I2C-compatible serial interface for real-time system management.
• Provides programmable current limiting and adjustable fault detection delays to protect against inrush currents and overcurrent conditions.
• Features input under-voltage lockout with hysteresis and a remote enable input for flexible system sequencing and control.

Hot Swap Controllers Applications

• Hot swap insertion for backplane systems requiring controlled power ramp-up
• Peripheral board protection in industrial computing environments
• Server and storage subsystem power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'PWR' confirms the tape-and-reel packaging format distinct from tube-packaged variants like 'PW'. Confirm RoHS compliance status and ensure the ordering part number matches the required package style for automated assembly processes. Cross-reference the manufacturer datasheet revision to validate functional parameters before final procurement.

Hot Swap Controllers Selection Notes

Select this component when precise digital power monitoring via I2C is required alongside standard hot swap protection. It is suitable for applications needing programmable current limits and fault response timing. Ensure the system voltage does not exceed the 36 V maximum rating and that the TSSOP-20 thermal performance meets the design requirements.

Hot Swap Controllers Part Context

This device belongs to the TPS2482 series of hot swap controllers, which are engineered for managing power insertion into live circuits. The series provides robust protection mechanisms including soft-start and current limiting. The PWR suffix specifically denotes the reel-based packaging configuration intended for high-volume surface-mount manufacturing lines.

Hot Swap Controllers Replacement Considerations
