Power Supply

13,24

VDD

-

Supply voltage; Connected to 5V voltage with reverse protection diode

and filter against EMC; Both pins must be connected to the supply without

parasitic resistors

1,2,11,12 GND

-

Ground; common ground for digital, analog and power; Pins must be

connected together without parasitic resistors

Cooling

TAB

GND

-

Cooling TAB (bottom side); Internally connected to ground; Pin must be

connected externally to ground without parasitic resistors
