Placing capacitor C1 across CAP1+ and CAP1-, across CAP2+ and CAP2-, across CAP3+
and CAP1-, across CAP4+ and CAP2-, across CAP5+ and CAP1-, across CAP6+ and
CAP2-, and across VOUT and VSS will boost the voltage coming from VEE and VSS nth
times and outputs the boosted voltage to the VOUT pin. The boosted voltage, either twice,
three times, four times or five times the supply voltage and which is output to the VOUT pin
is determined by the boost step register, and set by a command instruction.
When using a built-in booster circuit, the output voltage (VOUT) must be less than the
recommended operating voltage (20V).
recommended operating voltage, the proper and full functionality of the chip cannot be
guaranteed.
Booster Circuit
VEE=3V
VSS=0V
In case the required voltage is twice the voltage supply, this is achieve by placing
In case the required voltage is three times the voltage supply, this is achieve by
In case the required voltage is four times the voltage supply, this is achieve by
In case the required voltage is five times the voltage supply, this is achieve by
In case the required voltage is six times the voltage supply, this is achieve by
In case the required voltage is seven times the voltage supply, this is achieve by
