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.

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
J
(MAX) - T
A
)/
JA
. 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.
