TPS2350DR

Hot Swap Controllers Overview

The TPS2350DR is a hot swap power manager designed for redundant -48V supply systems. It operates within a supply voltage range of -12 V to -80 V and withstands transients up to -100 V. The device features three channels in a 14-SOIC package, with an operating temperature range of -40°C to +85°C. It includes programmable current limit, fault timeout, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO). The component utilizes internal power FETs to function as low voltage drop diodes, replacing OR-ing diodes in redundant configurations.

Hot Swap Controllers Feature Summary

• Withstands high-voltage transients up to -100 V for robust operation in harsh environments
• Integrates programmable protections including current limit, fault timeout, OVP, and UVLO
• Replaces OR-ing diodes using internal power FETs to minimize voltage drop

Hot Swap Controllers Applications

• Redundant -48V power supply systems
• Telecommunications infrastructure
• Industrial control systems requiring hot swap capability

Hot Swap Controllers Procurement Notes

Verify the specific suffix DR indicates the 14-SOIC package variant when sourcing. Confirm RoHS compliance status through official Texas Instruments documentation or authorized distributors. Ensure the ordering part number matches the required channel count and package type for your PCB layout. Cross-reference the datasheet revision to ensure all electrical characteristics align with your design requirements before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component for applications requiring redundant -48V architectures where hot swap functionality is critical. The integrated power FETs offer lower voltage drop compared to traditional diode solutions. Consider the programmable features for customizing protection thresholds. Ensure the system voltage stays within the -12 V to -80 V operating range and accounts for transient spikes up to -100 V.

Hot Swap Controllers Part Context

The TPS2350 series serves as a power manager for redundant supplies. The TPS2350DR specifically denotes the SOIC package version. It is part of Texas Instruments' portfolio for managing power insertion and removal safely. Other variants like TPS2350PWR exist with different packaging but similar core functionality.

Hot Swap Controllers Replacement Considerations

TPS2350PW is a pin-compatible alternative in TSSOP-14 package. TPS2350DRG4 is the lead-free version of the same device. Verify package dimensions and thermal performance differences when substituting.
