Information

The LM25061-2 positive hot swap controller provides intelligent control of the power supply voltage to the load during insertion and removal of circuit cards from a live system backplane or other "hot" power sources. The LM25061 provides in-rush current control to limit system voltage droop and transients. The current limit and power dissipation in the external series pass N-Channel MOSFET are programmable, ensuring operation within the Safe Operating Area (SOA). The POWER GOOD output indicates when the output voltage exceeds a programmable threshold. The input under-voltage level and hysteresis are programmable, as well as the initial insertion delay time and fault detection time. LM25061-2 automatically restarts at a fixed duty cycle. The LM25061 is available in a 10 pin VSSOP package.

Key Features

  • Operating Range: +2.9V to +17V
  • In-rush Current Limit for Safe Board Insertion into Live Power Sources

  • Internal High Side Charge Pump and Gate Driver for External N-Channel MOSFET
  • Adjustable Under-Voltage Lockout (UVLO) and Hysteresis
  • Adjustable Output Voltage Monitoring and Hysteresis
  • Initial Insertion Timer Allows Ringing and Transients to Subside After System Connection
  • Programmable Fault Timer Avoids Nuisance Trips
  • Active High Open Drain POWER GOOD Output
  • Available in Latched Fault and Automatic Restart Versions
  • Package VSSOP-10
