Ordering Information/Selector Guide
Typical Operating Circuit
General Description
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).
The MAX14575A/MAX14575AL/MAX14575B/MAX14575C
are available in a small 8-pin, 2mm x 2mm TDFN pack-
age and operate over the -40NC to +85NC extended
temperature range.
