TABLE A: PIN CONFIGURATIONS
NOTE: the limited pin availability of the PowerSO-10 package leads to drop some functions.
ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is
not implied.

Logic control input: see truth table
Logic output (open collector). Normally in HIGH
IMPEDANCE, goes LOW when current or thermal overload
occurs
In stand-by mode, the voltage on MI is routed to LNBA pin.
Can be left open if bypass function is not needed
