LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); all DC levels are referenced to GND.
Note
1.
Mostly dependent on the maximum required ambient temperature, on the voltage between LN and SLPE and on the
thermal resistance between die ambient temperature. This thermal resistance depends on the application board
layout and on the materials used. Figure 17 shows the safe operating area versus this thermal resistance for ambient
