NOTE:

During charging, the voltage could rise as high as 9.4V and all circuitry connected to the battery must be
designed to operate up to this voltage.

A block diagram for a four cell power supply is shown in figure 2 below, note that the battery voltage is stepped-up
to power 5V SIM cards or the 5V RF power amplifier. This circuit also shows a Power-On-Reset (POR) to hold the
CPU in a reset state while the supply voltage and system clock stabilize.
