TPS2399DGKR

Hot Swap Controllers Overview

The TPS2399DGKR is a hot swap controller designed for redundant -48 V supply systems. It operates within a supply voltage range of -36 V to -80 V and withstands transients up to -100 V. Key electrical parameters include a maximum operating temperature of +85 °C, a minimum of -40 °C, and a supply current of 700 µA. The device features programmable current limit, fault timer, and slew rate control. It utilizes an 8-pin VSSOP package.

Hot Swap Controllers Feature Summary

• Optimized for redundant-supply systems with rapid short-circuit protection
• Programmable peak magnitude limiting and load current slew rate
• Integrated fault timer to eliminate nuisance trips during system switchover

Hot Swap Controllers Applications

• -48 V distributed power systems
• Redundant negative voltage supplies
• Central office switching applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix DGKR corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the component meets RoHS3 standards as indicated in manufacturer documentation. Ensure compatibility with external N-channel FETs and sense resistors for proper circuit operation.

Hot Swap Controllers Selection Notes

Select this component when designing for redundant -48 V architectures requiring robust transient tolerance. It is suitable for environments where plug-in modules must tolerate voltage spikes during switchover. Compare against TPS2390 if automatic retry functionality is not required.

Hot Swap Controllers Part Context

This part belongs to the TPS239x family of simple hot swap controllers from Texas Instruments. It shares the core architecture with the TPS2390 but adds specific features for redundant systems. The DGKR suffix indicates the VSSOP-8 surface-mount package variant.

Hot Swap Controllers Replacement Considerations

TPS2390DGKR is a related single-channel controller but lacks the redundant supply optimization features.
