APPLICATION NOTE 3209
Protecting Against Momentary Power Loss Due to Battery-Bounce

Impact or vibration can cause momentary interruptions when batteries lose contact. To ensure continuity of
power in battery-powered systems, add this three-IC circuit.


When you drop a battery-powered device, the impact can open internal contacts for as long as 10ms, producing
a momentary loss of power that can cause a false low-battery indication. (There is sometimes a similar
momentary effect on the device's owner, especially if the device is expensive, but that's beyond the scope of this
application note).


You can insure continuity of
