The Future of Analog IC Technology
MP62130/MP62131
3.3V/5V, Single-Channel 500mA
Current-Limited Power Distribution Switch
with Output Discharge
DESCRIPTION
The MP62130/MP62131 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62130/MP62131
Analog switch features 90mΩ on-resistance
and operates from 2.7V to 5.5V input. It is
available with a guaranteed current limit,
making it ideal for load switching applications.
The MP62130/MP62131 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, the device will shut off. The device
will recover once the device temperature
reduces to approx 120°C.
The MP62130/MP62131 is available in MSOP8
and SOIC8 packages.
