LTC1642IGN#PBF

Hot Swap Controllers Overview

The LTC1642IGN#PBF is a hot swap controller housed in a 16-lead SSOP package. It supports adjustable current limiting thresholds and operates within an ambient temperature range of up to 85 °C. The device functions as a power supply support circuit with one channel and one function, featuring a maximum operating temperature of 85 °C and a length of 4.8895 mm. It complies with RoHS standards and has a moisture sensitivity level of 1.

Hot Swap Controllers Feature Summary

• Provides adjustable current limiting for controlled insertion into live backplanes
• Functions as a dedicated power supply support circuit for hot swap applications

Hot Swap Controllers Applications

• Hot swap systems requiring controlled board insertion
• Backplane power distribution management
• Power supply support circuits in modular equipment

Hot Swap Controllers Procurement Notes

Verify the specific suffix IGN#PBF against official Analog Devices documentation to confirm the commercial temperature grade and tape-and-reel packaging format. Ensure compatibility with system thermal requirements given the 85 °C maximum operating limit. Cross-reference the manufacturer part code GN with the datasheet to validate pinout and mechanical dimensions before integration.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require precise control over inrush current during module insertion. The adjustable threshold feature allows customization for different load profiles. Verify that the 16-lead SSOP package fits the available PCB footprint and that the 85 °C temperature rating meets the environmental constraints of the target application environment.

Hot Swap Controllers Part Context

This part belongs to the LTC1642 series from Linear Technology, now part of Analog Devices. It is designed specifically for managing the safe insertion and removal of circuit boards in powered systems. The series focuses on protecting both the system bus and the inserting card from damage due to excessive current spikes during connection.
