TPS2480PWR

Hot Swap Controllers Overview

The TPS2480PWR is a positive voltage hot-swap controller manufactured by Texas Instruments, designed to minimize inrush current and protect loads from over-current or short-circuit events. It operates within an input voltage range of 9 V to 20 V and features programmable FET power and current limits to ensure the external N-channel MOSFET remains within its Safe Operating Area (SOA). The device includes a programmable fault timer, open-drain Power Good output, and high-accuracy I2C monitoring for current, voltage, and power with dynamic calibration.

Hot Swap Controllers Feature Summary

• Controls an external N-channel MOSFET switch to manage inrush current and provide intelligent protection against over-current and short-circuit conditions.
• Provides accurate monitoring of current, voltage, and power via an I2C interface using a configurable 12-bit A/D converter.
• Features independently adjustable power and current limits to maintain the external MOSFET operation within its Safe Operating Area.

Hot Swap Controllers Applications

• Server systems
• Hard disk drives
• Storage networks
• Base stations

Hot Swap Controllers Procurement Notes

Verify that the specific suffix 'PWR' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'PW' version. Confirm the component's RoHS compliance status through official manufacturer documentation before finalizing procurement orders. Ensure the selected package matches the intended PCB footprint requirements.

Hot Swap Controllers Selection Notes

Select this controller when precise management of inrush current and load protection is required for positive voltage applications. It is suitable for designs needing accurate real-time monitoring of electrical parameters via digital interfaces. Consider the requirement for an external N-channel MOSFET and the need for programmable fault timers to prevent nuisance shutdowns during transient events.

Hot Swap Controllers Part Context

The TPS2480PWR belongs to the TPS2480 series of hot-swap voltage controllers. This family is engineered to provide intelligent protection for downstream loads while allowing controlled power-up sequences. The device integrates essential functions for managing power delivery in sensitive electronic environments.

Hot Swap Controllers Replacement Considerations

The TPS2481 serves as a related variant within the same product family, offering similar hot-swap control capabilities. Verify pinout compatibility and functional equivalence with the TPS2480EVM-002 evaluation module documentation before implementing any substitution.
