Descrição geral do produto

The ADM1170-1AUJZ-RL7 is a Hot Swap Controller that safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge pump is used to enhance the gate of the N-channel FET. When an overcurrent condition is detected, the gate voltage of the FET is reduced to limit the current flowing through the sense resistor. The ADM1170 operates with a supply voltage ranging from 2.7 to 16.5V. By using independent SENSE pins from VCC, the ADM1170 allows for the hot swap of supplies ranging down to 1.6V. During an overcurrent condition, the TIMER pin capacitor determines the amount of time the FET remains at a current limiting mode of operation until it is shut down. The ON (ON-CLR) pin is the enable input for the device and can be used to monitor the input supply voltage.
  • Allows protected board removal and insertion to a live backplane
  • External sense resistor provides adjustable analog current limit with circuit breaker
  • Soft start controls inrush current profile
  • Peak fault current limited with fast response
  • Charge pumped gate drive for external N-FET switch
  • Automatic retry or latch-off during current fault
  • Undervoltage lockout
