Fleapower flasher draws less than 50 �A:
01/23/03 EDN-Design Ideas / Some applications
require a circuit to indicate that a battery's
voltage has fallen below a certain value. However,
if you don't frequently check the indicator, the
low-battery indicator itself can easily discharge
the battery. The circuit in Figure 1 indicates when
the battery voltage has dropped below a preset
value... |

Low battery indicator uses fleapower : 09/04/03
EDN-Design Ideas / It is always desirable to use a
low-battery indicator that consumes as little power
as possible. For a 9V, 450-mAhr alkaline battery, a
50-�A low-battery indicator can by itself run the
battery down in a little more than a year.
Battery-powered devices that need to run
continuously for a long time require battery
indicators that consume minimal power....

Motor controller uses fleapower : 09/25/03 EDN-Design
Ideas / A simple, permanent-magnet dc motor is an
essential element in a variety of products, such as
toys, servo mechanisms, valve actuators, robots, and
automotive electronics. In many of these
applications, the motor must rotate in a given
direction until the mechanism reaches the end of
travel, at which point the motor must automatically
stop... |
Reset generator uses "fleapower": 06/27/2002
EDN - Design Ideas / When a processor-controlled
device must operate reliably, designers often choose
to periodically reset the processor rather than rely
on a watchdog configuration. In low-power systems,
this periodic-reset circuit can consume a large part
of the system's current budget or may fail to
operate at low voltages.. |
