产品概述

The MAX5921FESA+ is a -48V hot swap controller with external RSENSE and high gate pull-down current in 8 pin NSOIC package. This hot swap controller allows a circuit card to be safely hot plugged into a live backplane. It operates from -20V to -80V and is well suited for -48V power systems. It is pin compatible with both the LT1640 and LT4250 and provides improved features over these devices. It provides a controlled turn-on to circuit cards preventing damage to board connectors, board components and preventing glitches on the power supply rail. Device ensure that input voltage is stable and within tolerance before applying power to load. This IC protects system against overcurrent and short circuit conditions by turning off external MOSFET in event of a fault condition. It is used in telecom line cards, network switches/routers, central-office line cards, server line cards and base-station line cards.
  • Operating temperature range from -40°C to 85°C
  • Circuit breaker immunity to input voltage steps and current spikes
  • 450mA GATE pull-down current during short circuit condition
  • Exponential GATE pull-down current, overcurrent fault integrator
  • Withstands -100V input transients with no external components
  • Programmable inrush and short circuit current limits, powers up into a shorted load
  • Programmable overvoltage protection, power good control output
  • Programmable undervoltage lockout with built-in glitch filter
  • Thermal shutdown protects external MOSFET
