4.4 Power management pins
The power management pins consist of the Power, Ground and Regulator pins.
VDD
VDD is a power pin and is the main power supply for the SX8661.
VDD has protection to GROUND.
Figure 48 shows a simplified diagram of the VDD pin.
GND
The SX8661 has four ground pins all named GND. These pins and the package center pad need to be connected
to ground potential.
The GND has protection to VDD.
Figure 49 shows a simplified diagram of the GND pin.
