8. ICONT Input Operation
As Figure 8 shows, when the VCONT terminal (pin 16) goes from “L” level to “H” level, the OUT1 terminal (pin
29) outputs its regulated voltage. Then, after a delay interval (85 ms (Typ.)) the XRST terminal (pin 35) goes to
“H” level.
If after the XRST terminal has gone to “H” level the ICONT terminal (pin 36) goes to “L” level, the MB3893A
goes into standby mode, reducing the IC internal current consumption. When the ICONT terminal returns to “H”
level normal operation is restored.
When the VCONT terminal goes from “H” level to “L” level, the OUT1 terminal goes to “L” level. At this time the
XRST terminal also goes to “L” level.
