Operation of Charge Pump Circuit
Initial charging
(1) When RESET is released, Tr1 is turned ON and Tr2 turned OFF. Ccp2 is charged from Ccp2 via Di1
(This is the same as when TSD and ISD are operating and the IC is restored from Reset state.)
(2) Tr1 is turned OFF, Tr2 is turned ON, and Ccp1 is charged from Ccp2 via Di2.
(3) When the voltage difference between VM and VH (CcpA pin voltage = charge pump voltage) reaches VDD or
higher, operation halts (Steady state: Because the capacitor is naturally discharged, the IC is continually
charging to the capacitor).
Actual operation
(4) Ccp1 charge is used at fchop switching and the VH potential drops.
(5) Charges up by (1) and (2) above.
