Features • Wide operating range: +9V to +80V • In-rush current limit for safe board insertion into live power sources • Programmable maximum power dissipation in the external pass device • Adjustable current limit • Circuit breaker function for severe over-current 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 connection • Programmable fault timer avoids nuisance trips • Active high open drain POWER GOOD output • Available in latched fault and automatic restart versions Description The LM5069 positive hot swap controller provides intelligent control of the power supply connections during insertion and removal of circuit cards from a live system backplane or other "hot" power sources. The LM5069 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 is within 1.25V of the input voltage. The input under-voltage and over-voltage lockout levels and hysteresis are programmable, as well as the initial insertion delay time and fault detection time. The LM5069-1 latches off after a fault detection, while the LM5069-2 automatically restarts at a fixed duty cycle. The LM5069 is available in a 10 pin MSOP package. Applications • Server Backplane Systems • Base Station Power Distribution Systems • Solid State Circuit Breaker • 24V/48V Industrial Systems

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
