MP6211-3/MP6212-3
3.3V/5V, Single-Channel 1A
Current-Limited Power Distribution Switch
The Future of Analog IC Technology
DESCRIPTION
The
MP6211-3/MP6212-3
single-channel
Power Distribution Switch features internal
current limiting to prevent damage to host
devices due to faulty load conditions. The
MP6211-3/MP6212-3 Analog switch has 95mΩ
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 MP6211-3/MP6212-3 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 FLAG output of MP6211-3/MP6212-3 will
report a fail mode (low level) when over current
or over temperature is encountered. The FLAG
will not change state when the input UVLO is
triggered.
The MP6211-3/MP6212-3 is available in 8-Pin
MSOP package with exposed pad and 8-Pin
SOIC8 package with exposed pad.
