MP62061
3.3V/5V, Single-Channel 700mA
Current-Limited Power Distribution Switch
The Future of Analog IC Technology
DESCRIPTION
The MP62061 Power Distribution Switch features
internal current limiting to prevent damage to host
devices due to faulty load conditions. The MP62061
Analog switch features 80mΩ on-resistance and
operates from 2.7V to 5.5V input. It is available with
a guaranteed current limit, making it ideal for load
switching applications. The MP62061 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, the device will shut off. The device will
recover once the device temperature reduces to
approx 120°C.
The MP62061 is available in MSOP8E and SOIC8E
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
θ
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
)/θ
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.
