On-demand mode

On-demand mode:

The On-demand mode is initiated by setting EOD bit (see Table 10). This mode is primarily intended to maximize battery lifetime in low duty cycle applications where the system is in sleep-mode most of the time. In this mode the energy is first extracted from the battery and stored in a capacitor (Cstore) connected to pin CAP. The stored energy is then made available at full power as a regulated supply voltage at pin VDH. The RDY output indicates when the output VDH is ready to deliver power. On-demand mode is ended by resetting the EOD and ACT bits.
