Please let me know about relation of pre charge (PCHG) and charge pump.
Is charge pump need to turn on before pre-charge enable?
I think that PCHG is not need timing of charge pump because Pch-FET, is it correct?
Charge (CHG) and discharge (DSG) function are need to turn on charge pump at first.
But PCHG was not written in the datasheet.
Best regards,
