LTC4228IGN-1#TRPBF

Hot Swap Controllers Overview

The LTC4228IGN-1#TRPBF is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It integrates two ideal diode controllers and hot swap controllers in a single SSOP-28 package. The device operates with a supply voltage range of 2.9V to 18V and draws a typical operating supply current of 2.5 mA. Key electrical features include programmable current limiting, adjustable fault timeout, and slew rate control. It provides latched fault protection and under-voltage lockout (UVLO) for robust system management.

Hot Swap Controllers Feature Summary

• Integrates dual channels combining ideal diode rectification and hot swap control capabilities within a single component.
• Provides comprehensive protection through latched fault handling, under-voltage lockout, and programmable current limiting.
• Offers precise power-up sequencing and surge management via adjustable fault timeout and controlled slew rate settings.

Hot Swap Controllers Applications

• General purpose hot swap applications requiring dual-channel power path management
• Systems utilizing ideal diode functionality for reverse polarity protection and load sharing
• Industrial equipment needing robust overcurrent and fault protection mechanisms

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm availability status as distribution channels may report limited stock or restricted supply conditions for this part number. Ensure compatibility with SSOP-28 footprint requirements during procurement planning.

Hot Swap Controllers Selection Notes

Select this component for designs requiring integrated dual-channel hot swap and ideal diode functions. The SSOP-28 package suits space-constrained surface mount applications. Verify that the 2.9V to 18V supply range aligns with system voltage rails. Consider the 2.5 mA supply current impact on overall power budget.

Hot Swap Controllers Part Context

This part belongs to the LTC4228 series of hot swap voltage controllers from Analog Devices. It is functionally related to other devices in the family but distinguished by its dual-channel configuration and specific pinout. The IGN-1 designation typically refers to the industrial temperature grade and specific package variant within the broader product line.

Hot Swap Controllers Replacement Considerations

Direct substitutes may include other dual-channel hot swap controllers from Analog Devices such as the LTC4228IGN-1#PBF for tube packaging. Cross-reference pinouts and electrical specifications carefully before substitution to ensure functional equivalence in the target application.
