产品概述

The MAX5944ESE+ is a dual FireWire current limiter and low-drop ORing switch controller in 16 pin NSOIC package. Each independent channel controls two external power MOSFETs to regulate current from the input power supply to the load and performs low voltage drop power-supply ORing. It allows safe insertion and removal of FireWire peripherals into a live FireWire port by providing inrush current control and output current-limiting functions. It features a current-limit function that actively limits the current drawn by the load with a 2ms timeout. Its autoretry function then automatically restarts after the 259ms autoretry delay time. The ORing feature provides a very efficient way to protect the FireWire port when connected to another FireWire peripheral that sources a higher voltage. By turning off the external MOSFETS, the MAX5944 provides a true bidirectional load disconnect. Each channel has an independent ON/OFF control that results in less than 10µA supply current per channel.
  • Supply voltage range is 7.5V to 37V
  • Operating temperature range from -40°C to 85°C
  • Low drop power ORing with ultra-fast turn-off
  • ±5% current limit sensing accuracy
  • Provides inrush and output current limit
  • Dual channel hot swap
  • Power routing from one port to another
