Operation of Charge Pump Circuit
z
Initial charging
(1) When RESET is released, T
r1
is turned ON and T
r2
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) T
r1
is turned OFF, T
r2
is turned ON, and Ccp1 is charged from Ccp2 via Di2.
(3) When the voltage difference between V
M
and V
H
(CcpA pin voltage
=
charge pump voltage) reaches V
DD
or
higher, operation halts (Steady state : Because the capacitor is naturally discharged, the IC is continually
charging to the capacitor).
z
Actual operation
(4) Ccp1 charge is used at fchop switching and the V
H
potential drops.
(5) Charges up by (1) and (2) above.
