DESCRIPTION
The MP62160/MP62161 Power Distribution
Switch features internal current limiting to
prevent damage to host devices due to faulty
load conditions. The MP62160/MP62161
operates from a 3.3V or 5V input voltage and
includes an 85m Power MOSFET to handle
up to 2A continuous load with a 2.8A typical
current limit. The MP62160/MP62161 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 MP62160/MP62161 involves a discharge
function that provides a resistive discharge path
for the external output capacitor when the part
is disabled.
The MP62160/MP62161 is available in QFN8E,
MSOP8E and SOIC8 packages.

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 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.
3) Measured on JESD51-7, 4-layer PCB.
