LT4250HIN8#PBF

Hot Swap Controllers Overview

The LT4250HIN8#PBF is a negative voltage hot swap controller designed for -48V systems. It operates with a supply voltage range of -80V to -18V and draws 1.6mA of supply current. The device is housed in an 8-pin PDIP package with a through-hole mounting style. It supports an operating temperature range from -40°C to 85°C and complies with RoHS3 standards.

Hot Swap Controllers Feature Summary

• Integrates programmable features including current limiting, fault lockout, overvoltage protection (OVP), and undervoltage lockout (UVLO).
• Provides fault timeout functionality to manage system protection events during hot swap operations.
• Designed specifically for negative voltage applications without requiring internal switches.

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Industrial power distribution systems
• Negative voltage hot swap control circuits

Hot Swap Controllers Procurement Notes

Verify the specific suffix HIN8 against the manufacturer's datasheet to confirm the PDIP package and commercial/industrial temperature grade. Confirm RoHS3 compliance status directly with the supplier or official documentation before procurement. Check for any recent product change notices regarding packaging or material declarations.

Hot Swap Controllers Selection Notes

Select this component for designs requiring precise control over negative voltage insertion sequences. Ensure the external circuitry supports the required current limiting and OVP thresholds. Verify that the 8-PDIP package fits the mechanical constraints of the target PCB layout. Consider the 1.6mA supply current impact on overall system power budget.

Hot Swap Controllers Part Context

This part belongs to the LT4250 family of hot swap controllers manufactured by Analog Devices Inc. It serves as a dedicated solution for managing power insertion in negative voltage environments, distinct from positive voltage counterparts like the LTC42xx series. The family focuses on robust protection and controlled ramp-up capabilities.
