Application Note: AN_SY6280
Low Loss Power Distribution Switch
TARGET DESIGN SPECIFICATION
Preliminary Spec
General Description
The SY6280 develops ultra-low Rds(on) switch with
programmable current limiting to protect the power
source from over current and short circuit conditions. It
integrates the over temperature protection and
discharges the output capacitor during the shutdown. In
case the output is pulled higher than the input voltage
under the shutdown, the SY6280 can block the current
flowing from the output to the input.

Note 1: Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device.
These are for stress ratings. Functional operation of the device at these or any other conditions beyond those
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may remain possibility to affect device reliability.
Note 2: θ JA is measured in the natural convection at TA = 25°C on a low effective single layer thermal
conductivity test board of JEDEC 51-3 thermal measurement standard. Pin 2 of SOT23-5 packages is the case
position for θ JC measurement.
Note 3: The device is not guaranteed to function outside its operating conditions
