APPLICATION FOR CELLULAR PHONES
(RV5VE0
×××
:Optional Mask Version)
This Optional Mask Version's application operates as follows.
Regulator 1, 2
: Regulator 1 and 2 can be enabled and disabled through Toggle Input and CPU signal CSW1.
Regulator 3
: Regulator 3 can be enabled and disabled through Toggle Input and CPU signal CSW2.
Regulator 4
: Regulator 4 is always enabled by dry cells (when the V
DD
voltage is maintained higher than
minimum operating voltage). The output of Regulator 4 is not only the power source for
CPU but also the level shift voltage of CSW 1, 2 pins. Therefor CSW1, 2 pins can be direct-
ly connected to CPU.
Detector 1, 2
: Detector 1 and 2 monitor the V
DD
level and the output of Regulator 4 respectively.
Furthermore Detector 2 can generate the output-delay time (time delay to output rising
edge) by connecting a capacitor to C
D
pin.
TFF
: TFF can be reset by the output of power-on-reset and Detector 2 (through one shot pulse
generator), while TFF is in the reset state Regulator 1, Regulator 2 and Regulator 3 are dis-
abled.
