ating with one or more NiCd/NiMH cells or one Li+ cell.
Adding a Manual Power Reset
A momentary pushbutton switch can be used to turn
the MAX1765 on and off (Figure 11). ONA is pulled low
and ONBis pulled high to turn the device off. When the
momentary switch is pressed, ONB is pulled low and
the regulator turns on. The switch must be pressed
long enough for the microcontroller (礐) to exit reset
and drive ONA high. A small capacitor is added to help
debounce the switch. The 礐 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 礐 to read the switch status and
pull ONA low. When the switch is released, ONB is
pulled high.
