General Description

The JW®7221 and JW®7221L are positive hot swap controllers that allows a board to be safely inserted and removed from a live backplane or other hot power sources.

JW7221/W7221L offers inrush current control to protect MOSFET against system voltage droop and transients.

The function of power limit protection allows better utilization of the external MOSFET’s SOA.

Key Features

  • Wide operating range: 9 V to 80 V.
  • Inrush current limit protection.
  • Programmable power limit.
  • Adjustable current limit: 55mV±11%.
  • Circuit breaker function for severe overcurrent events.
  • Internal high side charge pump and gate driver for external N-channel MOSFET.
  • Adjustable under-voltage lockout (UVLO) and hysteresis.
  • Adjustable over-voltage lockout (OVLO) and hysteresis.
  • Initial insertion timer allows ringing and transients to subside after system c.
