Anagear's Low-Power Circuits Harvest & Save Energy
1/22/2013

Anagear's ultra-low-power circuits are aimed at separating power management in low-power devices from the microcontroller in order to reduce the need for battery power and make way for alternative energy sources, such as solar power.   (Source: Anagear)

Great point Cabe, can you imagine if all those batteries were being tossed into landfills?

This reminds me of the solar powered calculators used in school. No one hails those as the alternative energy shining examples they were.

Something around 90% of all energy created is lose in various ways. Friction, heat, etc.. It is good companies are attempted to recover some of that. In the distant future, we will wish the past had.

Not if meets the right balance of cost and performance.  If it adds too much cost to the BOM then only the designs trying to squeeze every last nanowatt will want the part.  On the other hand, if they get the part under a dime in volume then I can use a cheaper, power guzzling micro and spend the dime on their part.  It's another performance/cost trade off.

It definitely seems like Anagear is on to something here with its preservation of power it manages by taking power management out of the microcontroller. It seems a fairly simplistic idea and will be interesting to see if this takes off. I wonder if designers might balk at making this change to the time-worn design.

Very true, so many designs simply need to wake up every second or so to make a measurement and that clock circuitry usually takes a few microamps.  Microcontroller vendors have gotten better at providing a low current wake-up but aren't really there yet. 
 
ZiLOG has a pretty nice watchdog circuit in their Encore parts that can do it with less than a microamp.
