Description
The LM73100 is a highly integrated circuit protection
and power management solution in a small package.
The device provides multiple protection modes using
very few external components and is a robust defense
against voltage surges, reverse polarity, reverse
current and excessive inrush current.

With integrated back-to-back FETs, reverse current
flow from output to input is blocked at all times,
making the device well suited for power MUX/ORing
applications. The device uses linear ORing based
scheme to ensure almost zero DC reverse current
and emulates ideal diode behavior with minimum
forward voltage drop and power dissipation.
Applications with particular inrush current
requirements can set the output slew rate with a
single external capacitor. Loads are protected from
input overvoltage conditions by cutting off the output if
input exceeds an adjustable overvoltage threshold.
The device also provides fast trip response to
transient overcurrent events during steady state.
The device provides an accurate sense of the output
load current on the analog current monitor pin.
The device is available in a 2-mm x 2-mm, 10-pin
HotRod QFN package for improved thermal
performance and reduced system footprint.
The device is characterized for operation over a
junction temperature range of –40°C to +125°C.
