The LM25061 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. The LM25061-1 latches
off after a fault detection, while the LM25061-2 automatically
restarts at a fixed duty cycle. The LM25061 is available in a
10 pin MSOP package.
