LTC4215IUFD-3#PBF

Hot Swap Controllers Overview

The LTC4215IUFD-3#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.9 V to 15 V and features adjustable current limiting for precise power distribution management. The device integrates I²C-compatible monitoring capabilities, allowing for real-time status reporting and configuration via a standard digital interface. Designed for surface-mount applications, it utilizes a QFN-24 package to facilitate compact PCB layouts. The component draws a typical operating supply current of 3 mA and supports retry functionality to manage transient fault conditions during system initialization or operation.

Hot Swap Controllers Feature Summary

• Integrates I²C-compatible monitoring interface for digital control and status feedback
• Provides adjustable current limiting to protect downstream loads from overcurrent events
• Supports retry functionality to automatically recover from transient faults

Hot Swap Controllers Applications

• Server and storage backplane power distribution
• Telecommunications equipment hot swapping
• Industrial control system module insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards as per manufacturer documentation. Confirm the IUFD designation matches the required industrial temperature grade and QFN-24 package variant. Cross-reference the datasheet revision to ensure compatibility with existing design specifications before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with integrated digital monitoring is required for systems operating up to 15 V. The adjustable current limit allows customization for various load profiles without external sensing resistors in many configurations. Ensure the QFN-24 thermal performance meets the application's dissipation requirements under maximum load conditions.

Hot Swap Controllers Part Context

This part belongs to the LTC4215 series of hot swap controllers, which are designed for safe insertion and removal of live circuit boards. The series offers various channel counts and monitoring options. The -3#PBF suffix typically denotes a specific pinout or feature set within the family, such as retry enablement, distinguishing it from other variants like the -1 or -2 models.

Hot Swap Controllers Replacement Considerations

Direct replacements include other LTC4215 variants such as LTC4215IUFD-1#PBF or LTC4215IUFD-2#PBF, provided the pinout and specific feature set (e.g., retry function) match the design requirements. Verify that any substitute maintains the same QFN-24 footprint and electrical characteristics.
