Power subsystem
Figure 8 shows an overview of the power subsystem architecture for CCG7D devices. The power subsystem of
CCG7D devices operate from VIN supply which can vary from 4 V to 24 V. The VDDD pin, the output of 5 V LDO gets
input from VIN supply. The VDDD pin can also be used as a power supply for external loads up to 150 mA. CCG7D
devices have two different power modes: Active and Deep Sleep, transitions between which are managed by the
power system. The VCCD pin, the output of the core (1.8 V) regulator, is brought out for connecting a 0.1-µF
capacitor for the regulator stability only. This pin is not supported as a power supply for external load.
