LTC4286 Datasheet High Power Positive Hot-swap Controller

Manufacturer: Analog Devices

Overview: Data Sheet LTC4286 High Power Positive Hot-Swap Controller with Power Monitor via.

General Description

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.

Key Features

  • Wide operating voltage range: 8.5 V to 80 V.
  • 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.
  • Peak 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 f.
