PowerSSO24
Although this package has two separate pins for the ground (pin11 = PGND = Power
Ground and pin22 = GND = Logic Ground), the device is designed to work with shortening
ground and is mandatory that the two pins have to be connected nearby the IC on the PCB.
The exposed slug must be soldered on the PCB and connected to GND.
