Low Energy Power Distribution

Figure 3-4shows the Low Energy Mode Power Dis- tribution. As stated earlier, the Low Energy 9VS is the source for the 5VS, 3.3V-ES and 3.3VS-1. The 5VS and 3.3VS-1 supplies power to the IC7A00 the PTV Control µPC.

The 3.3V-ES supplies power to the PTV Control cir- cuit E2PROM, now located on the PCB-TERMINAL.

The 9VS supply also provides power for the Antenna Relay in the RF Switch.
