Re: Charge pump simplifies this
OK - makes sense and seems quite reasonable. Good suggestion.

No - I am proposing another way of doing this. The proposed one is good. But if one wants to turn on higher voltages, say 32V as is done in MEMS, from low supply, charge pumps can be used to "step-up" the voltage.

Re: Charge pump simplifies this
Do you mean use a separate IC with separtae circuitry? Rather than using the boot circuitry contained in the IC already being used? Just want to clarify your comments.

It may be better to use charge pumps when one needs higher voltages internally. Charge pumps are excellent when there is a need to generate higher voltages internally.
