Power Supply Circuit
This power supply circuit is a low power supply
consumption one that generates the voltage required for
the liquid crystal drive and consists of a boosting circuit,
voltage adjusting circuit, and voltage follower circuit. It
is valid only at master operation.
The power supply circuit ON/OFF controls the boosting
• The boosting system pin indicates the CAP1+, CAP1–, CAP2+, CAP2–, or CAP3– pin.
• Although the combinations other than those listed in the above table are also possible, they cannot be recommended
Boosting circuit
The boosting circuit incorporated in the S1D15705
series enables the quadruple boosting, triple boosting,
and double boosting of the V
For the quadruple boosting, the V
is quadruple-boosted to the negative side and output to
the V
