the regulator turns on. The switch must be pressed
long enough for the microcontroller (μC) to exit reset
and drive ONA high. A small capacitor is added to help
debounce the switch. The μC issues a logic high to
ONA, which holds the device on, regardless of the
switch state. To turn the regulator off, press the switch
again, allowing the μC to read the switch status and
pull ONA low. When the switch is released,
ONB
is
pulled high.
