MP6231/MP6232
3.3V/5V, Dual-Channel 500mA
Current-Limited Power Distribution Switches
The Future of Analog IC Technology
DESCRIPTION
The MP6231/MP6232 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP6231/MP6232 analog
switch has 85mΩ on-resistance and operates
from 2.7V to 5.5V input. It is available with
guaranteed current limits, making it ideal for
load
switching
applications.
The
MP6231/MP6232 has built-in protection for both
over current and increased thermal stress. For
over current, the device will limit the current by
changing to a constant current mode.
As the temperature increases as a result of
short circuit, then the device will shut off. The
device will recover once the device temperature
reduces to approx 120°C.
The MP6231/MP6232 is available in 8-pin
MSOP, SOIC package with exposed pad and 8-
pin SOIC w/o exposed pad.
