Texas Instruments  LM5069MM-2/NOPB

The LM5069 positive hot swap controller provides intelligent control of the power supplyconnections during insertion and removal of circuit cards from a live system backplane or other hotpower sources. The LM5069 provides in-rush current control to limit system voltage droop andtransients. The current limit and power dissipation in the external series pass N-Channel MOSFETare programmable, ensuring operation within the Safe Operating Area (SOA). The POWER GOOD outputindicates when the output voltage is within 1.25 V of the input voltage. The input undervoltage andovervoltage lockout levels and hysteresis are programmable, as well as the initial insertion delaytime and fault detection time. The LM5069-1 latches off after a fault detection, while the LM5069-2automatically restarts at a fixed duty cycle. LM5069 is available in a 10-pin VSSOP package.
