Product Overview

The LTC4233HWHH#PBF is a low voltage SOA (safe operating area) hot swap controller in 38 pin QFN package. It is an integrated solution for hot swap applications that allows board to be safely inserted and removed from live backplane. The device integrates a hot swap controller, power MOSFET and current sense resistor in a single package for small form factor applications. The MOSFET safe operating area is production tested and withstands stresses in hot swap applications. The LTC4233 provides separate inrush current control and an 11% accurate 11.2A current limit with output dependent foldback. The current limit threshold can be adjusted dynamically using ISET pin. This hot swap controller includes current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and MOSFET temperature monitor output. The device has thermal limit, overvoltage, undervoltage and power good monitoring functions.
  • Wide operating voltage range from 2.9V to 15V
  • Safe operating area is provided at 41W, 30ms
  • Output current of 10A
  • 10mohm MOSFET including RSENSE
  • Current and temperature monitor outputs
  • Overtemperature protection
  • Adjustable current limit timer before fault
  • Adjustable inrush current control, power good and fault outputs
  • 2.5% accurate undervoltage and overvoltage protection
  • Operating ambient temperature range from -40°C to 125°C
