TPS2390DGK

Hot Swap Controllers Overview

The TPS2390DGK is a single-channel hot swap voltage controller 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-VSSOP surface-mount package. Key electrical characteristics include a supply current of 700 µA and integrated features such as programmable current limiting, fault timeout, and slew rate control.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting, fault timeout, and slew rate control for precise power-up management.
• Provides latch-off fault protection with undervoltage lockout (UVLO) for system reliability.
• Designed specifically for simple -48V hot swap applications without requiring internal switches.

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Industrial equipment power distribution
• Telecom base station power modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with -48V system requirements and thermal constraints. Confirm RoHS compliance status through the manufacturer's latest datasheet or product change notification before procurement.

Hot Swap Controllers Selection Notes

Select this component for designs requiring a dedicated controller for external N-channel MOSFETs in -48V environments. Consider the 8-VSSOP package for space-constrained PCB layouts. Evaluate the 700 µA supply current against system standby power budgets. Verify that external components can handle the specified voltage ranges.

Hot Swap Controllers Part Context

Part of the TPS239x series of hot swap controllers from Texas Instruments. This series focuses on protecting circuits during insertion and removal in live systems. The TPS2390DGK serves as a foundational controller for managing inrush current and overcurrent conditions in standard -48V architectures.

Hot Swap Controllers Replacement Considerations

TPS2390DGKR is a reel-based variant of the same controller. TPS2390DGKG4 indicates a lead-free version. Verify pinout and functional equivalence with any alternative -48V hot swap controllers from other manufacturers.
