Note 1. Exceeding the absolute maximum rating may damage the device.

Note 2. The device is not guaranteed to function outside its operating rating.

Note 3. Devices are ESD sensitive. Handing precautions recommended.

Note 4. For maintenance RDS≤140mΩ assembly to make gold conductors in diameter 50m.

Note 5. If there is a fault on one channel, that channel will shut down when the die reaches approximately 140

oC. If the

die reaches approximately 160

oC, both channels will shut down, even if neither channel is in current limit.
