DESCRIPTION
The MP62340/MP62341 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load
conditions.
The
MP62340/MP62341
analog switch has 80m 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
MP62340/MP62341 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 MP62340/MP62341 is available in 8-pin
MSOP package with exposed pad and SOIC
package without exposed pad.
