LTC4253A-ADJ Overview

Key Features

  • The LTC4253A-ADJ latches off after a circuit fault
  • The LTC4253A-ADJ’s supply input is shunt-regulated, allowing safe operation with very high supply voltages
  • A multifunction timer delays initial start-up and controls the circuit breaker’s response time
  • The circuit breaker’s response time can be accelerated by sensing excessive MOSFET drain voltage
  • An adjustable soft-start circuit controls MOSFET inrush current at start-up
  • Three power good outputs can be sequenced to enable external power modules at start-up or disable them if the circuit breaker trips
  • The LTC4253A-ADJ is available in 20-pin SSOP and 20-pin (4mm × 4mm) QFN packages
