TPS2350PWRG4

Hot Swap Controllers Overview

The TPS2350PWRG4 is a hot-swap power manager designed for redundant -48V supply applications. It operates within a supply voltage range of -80V to -12V and supports a maximum operating temperature of +85°C with a minimum of -40°C. The device features programmable current limiting, fault timeout, overvoltage protection (OVP), slew rate control, and under-voltage lockout (UVLO). It utilizes a 14-TSSOP surface-mount package.

Hot Swap Controllers Feature Summary

• Integrated hot-swap controller for managing power insertion in redundant -48V systems
• Programmable protection parameters including current limit, fault timeout, and slew rate
• Supports automatic retry functionality for transient fault recovery

Hot Swap Controllers Applications

• Redundant -48V telecommunications power supplies
• Hot-swap backplane power distribution
• Industrial equipment requiring controlled power insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead time requirements directly from the manufacturer's official documentation or authorized distributor catalogs. Confirm that the tape-and-reel packaging matches the design intent, as tube packaging may be available for other suffixes like 'PW'. Ensure the component meets all environmental standards required for the target deployment region.

Hot Swap Controllers Selection Notes

Select this component when designing redundant -48V architectures requiring precise control over inrush current and fault response times. The integrated UVLO and OVP features simplify board design by reducing external component count. Consider the 14-TSSOP package constraints for thermal management and PCB layout density compared to larger packages.

Hot Swap Controllers Part Context

This part belongs to the Texas Instruments TPS2350 family of hot-swap controllers. It is functionally equivalent to the TPS2350PW but differs in packaging format, typically utilizing tape-and-reel for automated assembly rather than tubes. The 'G4' suffix denotes Green/RoHS-compliant manufacturing.

Hot Swap Controllers Replacement Considerations

The TPS2350PW serves as a direct functional substitute with identical electrical characteristics, differing primarily in shipping packaging (tube vs. reel). Other variants such as TPS2350PWG4 share the same core specifications.
