Description
General part information
LTC4286 Series
The LTC4286 is an integrated solution for hot-swap applications allowing a board to be safely inserted and removed from a live backplane. The circuit breaker timer protects against metal-oxide semiconductor field-effect transistor (MOSFET) overheating, enabling reliable protection against overstress.The SMBus 3.1 interface, PMBus command structure, and onboard analog-to-digital converter (ADC) with selectable averaging and speed allow monitoring of board current, voltage, power, temperature, and fault status.The LTC4286 has additional features to respond to input undervoltage (UV) and overvoltage (OV): interrupts the host when a fault occurs, notifies when output power is good, detects insertion of a board, and auto-reboot after a programmable delay following a host commanded turn off.APPLICATIONSHigh availability server backplane systems12 V/24 V/48 V/54 V Distributed power systemsIndustrial
