TPS2390DGKG4

Hot Swap Controllers Overview

The TPS2390DGKG4 is a hot swap voltage controller designed for -48V telecommunications applications. It operates within a supply voltage range of -36V to -80V and features a single channel. The device is housed in an 8-VSSOP package with dimensions of 3x3mm. It functions across a temperature range of -40°C to +85°C. Key electrical characteristics include a supply current of 700 µA and support for programmable current limiting, fault timeout, and slew rate control.

Hot Swap Controllers Feature Summary

• Provides comprehensive protection for hot swap insertion into live backplanes
• Features adjustable thresholds for precise power management configuration
• Integrates undervoltage lockout (UVLO) and latch fault protection mechanisms

Hot Swap Controllers Applications

• -48V telecom system power distribution
• Telecommunications equipment backplane power modules
• Industrial control systems requiring hot swap capability

Hot Swap Controllers Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the VSSOP-8 package marking code matches the intended design requirements. Ensure the operating temperature range aligns with the target environmental conditions before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component for designs requiring robust protection in negative voltage environments. It is suitable where programmable parameters allow optimization for specific load profiles. Consider the 8-pin small outline package for space-constrained PCB layouts. Evaluate the need for external components to set timing and current limits based on system specifications.

Hot Swap Controllers Part Context

This part belongs to the TPS2390 series of simple hot swap controllers from Texas Instruments. It shares functional similarities with other models like the TPS2398 and TPS2390DGKR but differs in packaging and specific pin configurations. The series targets cost-sensitive applications needing reliable power path management without integrated switches.

Hot Swap Controllers Replacement Considerations

TPS2390DGKR serves as a tape-and-reel alternative offering identical electrical performance in the same package family.
