LTC4227IGN-2#TRPBF

Hot Swap Controllers Overview

The LTC4227IGN-2#TRPBF is a dual ideal diode and single hot swap controller manufactured by Analog Devices Inc. It operates within a 2.9V to 18V supply range and controls external N-channel MOSFETs for power path management. The device features a 16-lead SSOP package. Key electrical specifications include a peak fault current limit response time of ≤1µs, an ideal diode turn-on time of 0.5µs, and reverse turn-off time of 0.5µs. It provides adjustable current limiting with circuit breaker functionality and reports fault and power status.

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IGN-2 variant matches the required industrial temperature range and pinout compatibility for your design. Cross-reference the manufacturer's latest datasheet to ensure component compliance with current RoHS standards and any product change notifications that may affect lead or material composition.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring redundant power inputs or safe hot swapping capabilities on live backplanes. It serves as a low-loss replacement for high-power Schottky diodes, saving board area and heat sink requirements. Ensure the external MOSFETs selected can handle the regulated current limits and voltage drops specified in the official documentation for optimal efficiency.

Hot Swap Controllers Part Context
