LT1640LIS8#TRPBF

Hot Swap Controllers Overview

The LT1640LIS8#TRPBF is a negative voltage hot swap controller manufactured by Analog Devices. It operates within an input voltage range of 10 V to 80 V and draws a typical supply current of 1.3 mA. The device features programmable current limiting and is housed in an 8-pin SOIC package. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Manages power insertion for negative voltage rails to prevent system damage during hot swap events
• Provides programmable current limiting to control inrush currents during board insertion
• Integrates soft-start functionality to regulate the rate of voltage ramp-up

Hot Swap Controllers Applications

• Negative rail protection in telecommunications infrastructure equipment
• Hot swap module management in industrial control systems
• Power distribution units requiring controlled insertion of negative voltage cards

Hot Swap Controllers Procurement Notes

Verify the suffix TRPBF indicates tape and reel packaging with lead-free composition. Confirm the IS8 variant matches the required SOIC-8 footprint and thermal characteristics. Ensure the component meets RoHS directives for your specific manufacturing region before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when managing negative voltage buses up to 80 V. The programmable current limit allows customization for different load requirements. The wide operating temperature range suits harsh industrial environments. Verify that the single-channel configuration aligns with the target circuit design needs.

Hot Swap Controllers Part Context

This component belongs to the LT1640 series of hot swap controllers designed for negative voltage applications. It complements positive voltage counterparts like the LT1640HIS8#PBF. The series provides essential protection for modular systems where live insertion is required without disrupting active circuits.

Hot Swap Controllers Replacement Considerations

LT1640LIS8#PBF offers identical electrical specifications but utilizes tube packaging instead of tape and reel.
