产品概述

The MAX5947AESA+ is a positive high-voltage, hot-swap controller in 8 pin NSOIC package. This is fully integrated hot-swap controller for +9V to +80V positive supply rails allow for safe insertion and removal of circuit cards into live backplanes without causing glitches on backplane power-supply rail. During start-up, it acts as a current regulator using an external sense resistor and a MOSFET to limit amount of current drawn by the load. The UVLO threshold is adjustable using a resistive divider connected from VCC to ON to GND. It monitors input voltage, output voltage, output current and the die temperature. Device features power-good output to indicate status of output voltage by monitoring the voltage at FB. It is used in hot board insertion, electronic circuit breakers, industrial high-side switch/circuit breakers, network routers and switches and 24V/48V industrial/alarm systems.
  • Provides safe hot swap for +9V to +80V power supply range
  • Operating temperature range from -40°C to 85°C
  • Latched fault protection, maximum supply current of 3.5mA at VON = 3V, VCC = 80V
  • Low power good output logic
  • 8.3V default UVLO, overvoltage protection
  • Safe board insertion and removal from live backplanes
  • Programmable foldback current limiting
  • High-side drive for an external N-channel MOSFET
  • User-programmable supply voltage power-up rate
  • Built-in thermal shutdown
