DESCRIPTION
The MP62340-1/MP62341-1 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62340-1/MP62341-1
analog switch has 85m 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-
1/MP62341-1 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 MP62340-1/MP62341-1 involves discharge
function that provides a resistive discharge path
for the external output capacitor when the part
is disabled.
The MP62340-1/MP62341-1 is available in 8-
pin MSOP package with exposed pad and
SOIC package without exposed pad.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function o
f
themaximum junction temperature T
J
(MAX), the junction-
toambient thermal resistance
JA,
and the ambient
temperature T
A.
The maximum allowable continuous powe
r
dissipation at any ambient temperature is calculated by PD
(MAX) = (T

. Exceeding the maximum
allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
Internal thermal shutdown circuitry protects the device from
permanent damage.
