LTC4216IDE#PBF

Hot Swap Controllers Overview

The LTC4216IDE#PBF is a positive low voltage Hot Swap controller designed for safe board insertion and removal from live backplanes. It manages load voltages ranging from 0V to 6V and provides instantaneous analog current limiting to isolate severe faults. The device features an internal high-side switch driver for external N-channel MOSFETs, adjustable soft-start for inrush current control, and dual-level overcurrent protection with adjustable response time. Operating within a temperature range of -40°C to +85°C, it utilizes a 12-lead DFN package.

Hot Swap Controllers Feature Summary

• Provides instantaneous analog current limiting to isolate severe faults during hot swap operations
• Integrates an adjustable electronic circuit breaker with dual-level overcurrent protection
• Includes an internal high-side switch driver compatible with external N-channel MOSFETs
• Features adjustable soft-start capability to limit inrush current rates at startup

Hot Swap Controllers Applications

• Safe insertion and removal of boards from live backplanes
• Positive low voltage power supply management systems
• Load voltage regulation applications up to 6V

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact package type and temperature rating. Confirm RoHS compliance status through the manufacturer's product data sheet. Check current availability as distribution channels may report limited stock or discontinuation statuses that differ from official manufacturing schedules.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise control of low voltage loads between 0V and 6V. Ensure the design accommodates an external N-channel MOSFET, as the controller lacks an internal switch. Verify that the required soft-start timing and current limit thresholds align with the system's thermal and electrical constraints before finalizing the bill of materials.

Hot Swap Controllers Part Context
