LTC4227IUFD-1#TRPBF - Dual Ideal Diode and Hot Swap Controller
The LTC4227IUFD-1#TRPBF from Linear Technology is a sophisticated dual ideal diode and Hot Swap™ controller that provides a seamless power path management solution for systems with multiple power supplies. This compact, feature-rich device is engineered to facilitate safe board insertion and removal from a live backplane.
With its integrated dual ideal diode-OR and Hot Swap controller, the LTC4227 allows for the smooth transition between two power sources, which is vital for maintaining uninterrupted operation in redundant supply systems. The device's ideal diode function ensures low loss power ORing, while the Hot Swap capability allows a board to be safely inserted and removed from a live backplane by limiting inrush current.
Key Features:
- Dual Ideal Diode Controller: The LTC4227 provides low loss power path management between two power sources, minimizing power dissipation with its internal ideal diode MOSFETs.
- Hot Swap Controller: It offers precise control of the inrush current during board insertion and removal, protecting both the board and backplane from the potential damage caused by sudden surges of current.
- Wide Operating Voltage Range: The device operates over a broad voltage range from 2.9V to 18V, accommodating a variety of power systems.
- Adjustable Turn-On Time: Users can set the turn-on time with an external capacitor, which allows for customization based on specific system requirements.
- Status Indicators: The LTC4227 includes power good outputs and fault indication, providing essential feedback for system monitoring and diagnostics.
- Compact Package: Housed in a compact 24-lead QFN package, the LTC4227 is designed for space-constrained applications.
This product is ideal for systems that require reliable and efficient power distribution, such as servers, data storage systems, and telecommunications equipment. The LTC4227IUFD-1#TRPBF's combination of dual ideal diode and Hot Swap functionality ensures that systems remain operational even during supply transitions or board maintenance, making it a critical component for high-availability applications.
