TPS2350PW

Hot Swap Controllers Overview

The TPS2350PW is a hot swap voltage controller designed for redundant -48V power supplies. It operates within a supply voltage range of -80V to -12V and supports a single channel. The device features programmable current limiting, fault timeout, overvoltage protection (OVP), slew rate control, and under-voltage lockout (UVLO). It includes an automatic retry function and functions without internal switches. The component is housed in a 14-TSSOP package with dimensions of 5mm x 4.4mm x 1.15mm. It operates between -40°C and +85°C.

Hot Swap Controllers Feature Summary

• Provides comprehensive protection for redundant -48V power supply architectures through integrated fault detection and management capabilities.
• Offers fully programmable parameters including current limit thresholds, fault timeouts, overvoltage protection levels, and output slew rates for precise system tuning.
• Includes an automatic retry mechanism that restores power after transient faults, enhancing system availability and operational continuity.

Hot Swap Controllers Applications

• Redundant -48V telecommunications power systems
• Network routers and switching infrastructure
• Industrial control equipment requiring high reliability

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation when ordering, as variations such as PWG4 or PWR may indicate differences in packaging or RoHS compliance status rather than functional changes. Confirm the package type matches the design requirements, as the standard PW variant utilizes a tube package while other suffixes may utilize tape and reel configurations. Ensure compatibility with the target PCB footprint for the 14-TSSOP form factor.

Hot Swap Controllers Selection Notes

Select this component for applications requiring external N-channel MOSFET control in negative voltage environments. It is suitable where precise management of inrush current and fault response times is critical. Consider the operating temperature range and package thermal characteristics relative to the enclosure design. Verify that the external FET selection aligns with the programmable current limits and voltage ratings supported by the controller.
