TPS2398DGKRG4

Hot Swap Controllers Overview

The TPS2398DGKRG4 is a single-channel hot swap voltage controller manufactured by Texas Instruments, designed for -48V systems. It operates within a supply voltage range of -36V to -80V and supports an operating temperature from -40°C to +85°C. The device is housed in an 8-pin VSSOP package with surface mount installation. It belongs to the TPS2398 series and is RoHS compliant. This component functions as a dedicated controller for managing power insertion and removal in telecommunications and industrial applications without requiring internal switching elements.

Hot Swap Controllers Feature Summary

• Provides integrated control for safe hot swapping in negative voltage environments
• Includes programmable features for current limiting and fault timeout management
• Supports system protection through undervoltage lockout and latch-off fault mechanisms

Hot Swap Controllers Applications

• -48V telecommunications equipment power distribution
• Industrial control system power modules
• Telecom infrastructure hot swap backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix RG4 against official Texas Instruments documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm compatibility with your design specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when designing for -48V architectures requiring external FET switching. It is suitable for applications needing precise control over inrush current and fault response times. Consider the VSSOP-8 package constraints for thermal management and board space. Verify that the external components selected align with the controller's drive capabilities and timing requirements specified in the electrical characteristics.

Hot Swap Controllers Part Context

This component is part of the TPS2398 family of hot swap controllers. It complements other Texas Instruments power management solutions by providing the control logic necessary for safe power insertion. Unlike integrated power switches, it relies on external MOSFETs, offering flexibility in current handling capabilities while maintaining compact form factors for dense circuit designs.

Hot Swap Controllers Replacement Considerations

The TPS2390DGKR is a confirmed substitute within the same product family. Both devices share similar functional characteristics for -48V hot swap applications. Verify pin-to-pin compatibility and ensure that any differences in internal thresholds or timing parameters do not impact the existing circuit design before implementing the replacement.
