TPS2394PWR

Hot Swap Controllers Overview

The TPS2394PWR is a hot swap power manager designed for -48 V systems. It operates within a supply range of –12 V to –80 V and withstands transients up to –100 V. The device features a single channel with a typical operating supply current of 1 mA. It is housed in a TSSOP-14 package (PW) and supports an operating temperature range from –40 °C to +85 °C.

Hot Swap Controllers Feature Summary

• Manages hot swap power insertion for negative voltage systems
• Withstands high voltage transients up to –100 V
• Operates across a wide input supply range

Hot Swap Controllers Applications

• -48 V redundant power supplies
• Board power rails
• Industrial 12 V/24 V supplies
• Point-of-load converters

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'PWR' indicates the tape-and-reel packaging variant, distinct from the tube-packaged 'PW'. Confirm the component meets RoHS standards as listed in official specifications. Ensure the ordering part number matches the required package type and quantity format before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring robust transient protection and wide input voltage tolerance in negative voltage environments. The TSSOP-14 package offers a compact solution for space-constrained designs. Verify that the thermal performance and current handling capabilities align with the specific load requirements of the target system.

Hot Swap Controllers Part Context

This component belongs to the TPS2394 series of hot swap voltage controllers manufactured by Texas Instruments. It serves as a power manager for protecting circuits during insertion and removal in live systems. The device integrates control logic to manage power sequencing and fault conditions effectively.

Hot Swap Controllers Replacement Considerations

Check for direct substitutes within the same TI family or compatible pin-to-pin alternatives. Ensure any replacement maintains the –12 V to –80 V operating range and –100 V transient withstand capability. Verify package compatibility and thermal characteristics match the original design constraints.
