General Description
Benefits and Features
S Integrated Protection Reduces Board Space and
Makes Systems More Robust
The MAX14575A/MAX14575AL/MAX14575B/MAX14575C
programmable current-limit switches feature internal
current limiting to prevent damage to host devices due
to faulty load conditions. These current-limit switches
feature a low 32mI(typ) on-resistance and operate from
a +2.3V to +5.5V input voltage range. The current limit
is adjustable from 250mA to 2.5A, making these devices
ideal for charging a large load capacitor as well as for
high-current load switching applications.

Each device in the family handles an overcurrent event
differently depending on the option selected. The
MAX14575A/MAX14575AL feature an autoretry mode,
the MAX14575A has active high, and the MAX14575AL
has active-low EN polarity. The MAX14575B has latch-
off mode, and the MAX14575C features a continuous
current-limit mode. Additional safety features include
thermal shutdown protection to prevent overheating and
reverse current blocking to prevent current from being
driven back into the source (see the Selector Guide).
