Figure 5: Detailed Power Management Logic Block Diagram
The 73S1217F contains a power supply and converter circuit that takes power from any one of three
sources; VPC, VBUS, or VBAT.
VPC is specified to range from 2.7 to 6.5 volts. It can typically be supplied by a single cell battery with a
voltage range of 2.7 to approximately 3.1 volts or by a standard supply of 3.3 or 5 volts.
