TPS2350PWG4

Hot Swap Controllers Overview

The TPS2350PWG4 is a hot swap power manager designed for redundant -48V supplies, manufactured by Texas Instruments. It operates within a supply voltage range of -80V to -12V and features a single channel configuration. The device is housed in a 14-TSSOP surface-mount package with dimensions of 5mm x 4.4mm x 1.15mm. It supports an operating temperature range from -40°C to +85°C and draws a typical operating supply current of 2mA. Key programmable parameters include current limit, fault timeout, overvoltage protection (OVP), slew rate, and under-voltage lockout (UVLO).

Hot Swap Controllers Feature Summary

• Provides comprehensive protection for redundant -48V power systems through integrated control logic.
• Features fully programmable thresholds for current limiting, fault timeouts, and voltage protection levels.
• Supports automatic retry functionality to manage transient faults without manual intervention.

Hot Swap Controllers Applications

• Redundant -48V telecommunications power supplies
• Network routing equipment power management
• Industrial switching infrastructure

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance during procurement. Confirm the package type matches the required 14-TSSOP footprint. Ensure the supply voltage requirements align with the -80V to -12V operational range. Check for any specific ordering suffixes that may affect packaging or tape-and-reel specifications.

Hot Swap Controllers Selection Notes

Select this component when designing redundant -48V architectures requiring precise thermal and electrical protection. Consider the single-channel limitation if multiple independent rails need separate management. Evaluate the TSSOP-14 package constraints against board space limitations. Verify that the programmable feature set meets the specific fault response requirements of the target system.

Hot Swap Controllers Part Context

The TPS2350 series serves as a specialized power management solution for high-reliability applications. The TPS2350PWG4 variant specifically denotes the lead-free, RoHS-compliant version of the standard TPS2350 controller. It belongs to the broader family of hot swap controllers developed for telecom and industrial standards.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers include TPS2350PW, TPS2350PWR, and TPS2350PW RG4. These variants share identical functional descriptions and pinouts but may differ in packaging format or environmental compliance markings.

Hot Swap Controllers FAQ

Does the TPS2350PWG4 contain internal switches?

No, the device is a controller only and requires external N-channel MOSFETs for power path switching.

What is the maximum supply voltage for this component?

The maximum supply voltage is -12V, while the minimum operating voltage is -80V.
