LM25069PMME-2

• Operating range: 2.9 V to 17 V
• Inrush current limits for safety board insertion into the field power supply
• Maximum power consumption for programmable external devices
• Adjustable current limit
• Circuit breaker function serious overcurrent events
• The internal high-voltage side charge pump is driven by an external N-channel MOSFET gate
• Adjustable undervoltage lockout (UVLO) and hysteresis
• Adjustable overvoltage lockout (OVLO) and hysteresis
• The initial insertion timer allows the ringing and the connection of the system after the transient subsides
• Programmable fault timer to avoid nuisance
• The high-level drain open-circuit power output is good
• Available in locking faults and auto-reboot versions

illustrate

LM25069 actively hot-swappable controller provides intelligent control of the supply voltage from a live system backplane or other "hot" power source load during insertion and removal of the circuit card. LM25069 provides inrush current control to limit system voltage drops and transients. The programmable current limit and the power consumption of the external series of pass-through N-channel MOSFETs ensure safe operating area (SOA) operation. When the input voltage is 1.3V, it is an indication of the normal output of the power supply. Input undervoltage and overvoltage lockout levels and hysteresis are programmable, as well as as as initial insertion delay time and fault detection time. After the LM25069-1 latch, the fault is detected, while the LM25069-2 automatically restarts at a fixed duty cycle. LM25069 in a 10-pin MSOP package.
