Product Overview

The LTC4215CUFD#PBF is a Hot Swap Controller allows a board to be safely inserted and removed from a live backplane. Using an external N-channel pass transistor, board supply voltage and inrush current are ramped up at an adjustable rate. An I²C interface and onboard ADC allow for monitoring of load current, voltage and fault status. The device features adjustable foldback current limit and a soft-start pin that sets the dI/dt of the inrush current. An I²C interface may configure the part to latch off or automatically restart after the LTC4215 detects a current limit fault. The controller has additional features to interrupt the host when a fault has occurred, notify when output power is good, detect insertion of a load card and power-up either automatically upon insertion or wait for an I²C command to turn on. It has a 20µs circuit breaker filter for applications that require a fast fault response time and it defaults to latch-off after an overcurrent fault.
  • 8-bit ADC monitors current and voltage
  • dI/dt Controlled soft-start
  • High side drive for external N-channel MOSFET
  • No external gate capacitor required
  • Input overvoltage/undervoltage protection
  • Optional latch off or auto-retry after faults
  • Alerts host after faults
  • Inrush current limit with foldback
