Note: 1. Mostly dependent on the maximum required Ta and the voltage between LN and SLPE (see Figs 6 ).

2. Calculated for the maximum ambient temperature specified Ta=75

°C and a maximum junction temperature

of 125

°C.

3. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.
