DESCRIPTION
The MP62260-1/MP62261-1 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62260-1/MP62261-1
operates from 2.7V to 5.5V nominal input
voltage and includes a 45m
Power MOSFET
to handle up to 2A continuous load with a 3A
typical current limit. The MP62260-1/MP62261-
1 has built-in protection for both over current
and increased thermal stress. For over-current
protection (OCP), the device will limit the
current by going into a constant current mode.
When continuous output overload condition
exceeds power dissipation of the package, the
thermal protection will shut the part off. The
device will recover once the device temperature
reduces to approx 120°C.
The MP62260-1/MP62261-1 involves output
discharge function that provides a resistive
discharge path for the external output capacitor
when the part is disabled.
The MP62260-1/MP62261-1 is available in
SOIC8 package.
