The Future of Analog IC Technology
MP62170/MP62171
3.3V/5V, Single-Channel 1.5A
Current-Limited Power Distribution Switch
DESCRIPTION
The MP62170/MP62171 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62170/MP62171
analog switch has 75mΩ 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
MP62170/MP62171 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.
MP62170/MP62171 is available in 8-pin MSOP
and SOIC package without exposed pad.
