Pushbutton On/Off Controller Includes Optional Automatic
Turn-On When Handheld Device is Plugged In
Vui Min Ho It is well-known that most mechanical pushbutton
switches bounce when pressed, and that a debounce
circuit is required to produce a clean, usable signal from
the pushbutton. There are many debounce solutions
availableвЂ”common ones use flip-flops or R-S latchesвЂ”but
designing and implementing a debounce circuit is not as
trivial as it might seem, especially for handheld devices.
Because a pushbutton debounce circuit
must remain on all the time, a low supply
current is critical for battery-powered
handheld devices. Additionally, the circuit
should be capable of accepting power
from any available standby supply voltage without requiring a linear regulator.
Furthermore, the pushbutton input should
be able to withstand high ESD levels during
operation since it is usually connected
where contact with the human finger is
possible. And finally, the circuit must be
small enough to fit into whatever little
space is left on the printed circuit board.
The LTC2955 pushbutton controller covers …
