Reset Circuit
Power Supply Decoupling
A simple power-up reset circuit with about a 50µs reset active
(low) time is shown in Figure 5. Resistor R is used for protec-
P
tion only. The reset time is not critical but should be greater
than 300ns.
The PT7A4401C has two V_CC pins and two GND pins. Power
decoupling capacitors should be included as shown in Figure
6.
