S1D15E06 Series
2When used by switching between the double step-up
and VOUT = VDD using a command:
Capacitors C1 are connected between CAP1+
<-> CAP1 and between VDD <-> VOUT for use.
3Only VOUT = VDD is used.
6.6.1 Step-up circuit
VDD-VSS potential can be triple and double step-up by
the step-up circuit built in the S1D15E06 series. The
status of VOUT = VDD can be selected by stopping the
operation of the triple and double step-up circuit using
the command
VDD pin and VOUT pin are connected for use.
1When used by switching between the triple, double
step-up and VOUT = VDD using a command:
Capacitors C1 are connected between CAP1+
<-> CAP1, between CAP2+ <-> CAP2 and
between VDD <-> VOUT for use.
