TPS2321IPWR

Hot Swap Controllers Overview

The TPS2321IPWR is a dual-channel hot swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 13 V and supports independent circuit breaking for each channel. The device features an active high enable input and latched fault protection mechanisms. It is housed in a 16-pin TSSOP (PW) package, suitable for surface mount applications. The operational temperature range extends from -40°C to +85°C, with quiescent currents specified at 200 µA and 1 mA depending on the operating mode.

Hot Swap Controllers Feature Summary

• Dual-channel architecture providing independent control and circuit breaking capabilities for separate power rails
• Integrated latched fault protection that maintains state until explicitly cleared via the enable pin
• Active high enable logic allowing straightforward interface with system control signals

Hot Swap Controllers Applications

• General purpose hot swap power distribution systems
• Industrial equipment requiring controlled power sequencing
• Telecommunications infrastructure power modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix IPWR corresponds to the TSSOP-16 package and tape-and-reel quantity when ordering. Confirm the revision status against the latest Texas Instruments datasheet SLVS276F to ensure compatibility with current design requirements. Check for any recent product lifecycle notices or obsolescence warnings before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when dual independent hot swap channels are required within a 3 V to 13 V input range. The TSSOP-16 package offers a compact solution for space-constrained designs. Ensure the application benefits from latched fault protection and active high enable logic. Compare thermal performance and current limits against specific load requirements to validate suitability.

Hot Swap Controllers Part Context

The TPS2321 belongs to the TPS232x family of dual hot swap controllers from Texas Instruments. It shares functional similarities with the TPS2320 but includes specific enhancements for independent channel operation. This series is designed for robust power management in environments requiring safe insertion and removal of powered circuits without disrupting system operation.

Hot Swap Controllers Replacement Considerations

The TPS2321ID serves as a pin-compatible alternative in a SOIC-Narrow-16 package. Verify package dimensions and thermal characteristics when substituting between TSSOP and SOIC variants. Ensure electrical parameters remain within acceptable limits for the target application.
