DESCRIPTION
The MP62170/MP62171 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62170/MP62171
analog switch has 75m 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
MP62170/MP62171 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.
MP62170/MP62171 is available in 8-pin MSOP
and SOIC package without exposed pad.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) Measured on JESD51-7， 4-layer PCB.
