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. The low side MOSFET body diode forward current must be lower than 1mA

Note 3. θJA is measured in the natural convection at TA = 25°C on a high effective four layers thermal conductivity test board of

JEDEC 51-7 thermal measurement standard. The measurement case position of θJC is on the exposed pad of the

package.

Note 4. Devices are ESD sensitive. Handling precaution is recommended.

Note 5. The device is not guaranteed to function outside its operating conditions.
