TPS2390DGKR

Hot Swap Controllers Overview

The TPS2390DGKR is a single-channel hot swap controller designed for -48V systems, manufactured by Texas Instruments. It operates within a supply voltage range of -36V to -80V and features an internal current limit with programmable fault timeout and slew rate control. The device utilizes an 8-VSSOP package (3.00mm width) and supports surface mount installation. It functions across a temperature range of -40°C to +85°C with a typical supply current of 700 µA. Key protection mechanisms include under-voltage lockout (UVLO) and latch-off fault handling.

Hot Swap Controllers Feature Summary

• Programmable current limiting with adjustable fault timeout and slew rate control
• Integrated under-voltage lockout (UVLO) for power rail monitoring
• Latch-off fault protection mechanism to secure system integrity during errors

Hot Swap Controllers Applications

• -48V telecommunications infrastructure equipment
• Industrial control systems requiring hot swap capability
• Embedded systems needing controlled power insertion

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix 'DGKR' corresponds to the tape and reel packaging format. Confirm that the component meets RoHS3 compliance standards as indicated in official documentation. Ensure the 8-VSSOP package dimensions align with the target PCB footprint requirements before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise management of inrush current and overcurrent events in negative voltage environments. The integrated programmability allows customization of protection thresholds without external components. Consider the 700 µA supply current for low-power standby requirements and verify compatibility with the target MOSFET gate drive capabilities.
