4 Electrical Characteristics
Note: All voltages at pins 2 to 14 are measured with respect to ground GNDCC (pin 15). All voltages at pin 20 to
pin 36 and TAB are measured with respect to ground GNDbb (pin 19). The voltage levels are valid if other
ratings are not violated. The two voltage domains V
CC
and V
bb
are internally galvanic isolated.
4.1 Absolute Maximum Ratings
Note: Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction of
the integrated circuit. For the same reason make sure, that any capacitor that will be connected to pin
2
(VCC) and TAB (Vbb) is discharged before assembling the application circuit. Supply voltages higher than
V
bb(AZ)
require an external current limit for the GNDbb pin, e.g. with a 15 Ω resistor in GNDbb connection.
Operating at absolute maximum ratings can lead to a reduced lifetime.
