Extra Ship Charges May Apply Product Highlights > LTC4286 Positive Hot Swap Controller LTC4286 Positive Hot Swap Controller Analog Devices' LTC4286 is a high power positive hot swap controller with power monitor via PMBus ADI's 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. To respond to input undervoltage (UV) and overvoltage (OV), the LTC4286 interrupts the host when a fault occurs, notifies when output power is good, detects board insertion, and auto-reboots after a programmable delay following a host-commanded turn-off. EVAL-LTC4286-A1Z is a fully featured evaluation board for the LTC4286. The board layout provides a clear example of all the peripheral components and the hot-swap power path. The layout also maximizes the ability of the board to dissipate heat for some of the key components on the power path, allowing the evaluation of high-current hot-swap setups. Features Monitors currents, voltages, and power with ADC Adjustable 5% accurate current limit: 6 mV to 20 mV Current foldback limits MOSFET power dissipation for overstress protection Monitors VGS and VDS for MOSFET health Peaks detect registers for current, voltage, and power Reports input or output power Remote temperature sensing with programmable warning and shutdown thresholds ±1% accurate, 12-bit ADC for IOUT, VIN, and VOUT Available in 39-lead, 7 mm x 7 mm, QFN package Applications 12 V/24 V/48 V/54 V distributed power systems Industrial Image 156 - Immediate Co-Browse By using the Co-Browse feature, you are agreeing to allow a support representative from DigiKey to view your browser remotely.
