LTC4221IGN#PBF

Hot Swap Controllers Overview

The LTC4221IGN#PBF is a dual-channel Hot Swap controller manufactured by Analog Devices Inc. It enables safe insertion and removal of boards from live backplanes using two independent high-side gate drivers. The device operates within a supply voltage range of 1 V to 36 V and features an operating temperature range of -40°C to +85°C. Key electrical parameters include an operating supply current of 2.2 mA. It is housed in a 16-lead SSOP package with a width of 3.90 mm, designed for surface-mount technology applications requiring precise power management.

Hot Swap Controllers Feature Summary

• Provides independent high-side gate control for two channels to manage board insertion and removal safely.

Hot Swap Controllers Applications

• Safe insertion and removal of circuit boards from live backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SSOP-16 package dimensions match your PCB footprint requirements. Ensure the input voltage range aligns with your system's 1 V to 36 V operational limits. Check for any recent product change notifications that might affect pinout or specifications.

Hot Swap Controllers Selection Notes

Select this component for applications requiring dual-channel hot swap protection with low quiescent current. It is suitable for systems needing robust overvoltage and undervoltage lockout protection. Consider the 16-SSOP package size for space-constrained designs. Verify compatibility with the target backplane voltage levels before integration.
