Charging circuitry

The figure below shows the internal charging circuit. It is controlled via the WXODIO pin of

Dolphin V4 which switches according to the status of the internal threshold detector. For

details please refer to the Dolphin V4 Core Description documentation. The WXIDIO pin is

used to disconnect the energy storage element at voltages below VOFF to avoid deep dis-

charge.

An external 3 V backup battery can be connected at VCHAR.
