Frequently Asked Questions
What supply voltage range does the LTC4252-2 support for hot-swap control?
The LTC4252-2 is designed to operate with negative 48V supply rails, which is the standard voltage used in telecom and networking backplane systems. It controls 2 channels of hot-swap power management, enabling safe live board insertion at -48V.
How does the LTC4252-2 protect against inrush current during board insertion?
The LTC4252-2 limits inrush current by controlling an external N-channel MOSFET gate, gradually ramping the voltage across the load over a controlled time period. The adjustable threshold allows engineers to set overcurrent limits by selecting a resistor value, typically targeting current limits in the range of a few amperes to protect sensitive components.
Which industrial and telecom applications is the LTC4252-2 best suited for?
The LTC4252-2 is ideal for -48V telecom central office equipment, high-availability routers, and networking line cards where live board swap is required. Its 2-channel design and MSOP-8 package make it a compact solution for systems with up to 2 independent hot-swap power rails operating at -48V.
