LTC4286

Overview

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.

  • 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 for IOUT, VIN, and VOUT
  • Available in 39-lead, 7 mm x 7 mm, QFN package
