@Etmax: Domo Arigato. That is very interesting. I liked it very much and will get one.

Seiko already makes a watch called the Seiko Kinetic perpetual that uses a small dyno to charge the battery, Check out this video for some amazing facts about it http://www.youtube.com/watch?v=PYMZANXDBbs. It's been out for a while, so I don't think it uses this IC particularly.

Can this IC be used in Wrist Watch Application to power it perpetually? Is there any commercially available Wrist Watch with PMIC?

Combination of all different types of energy-harvesting sources in a single package is a great thing to have. I'm not sure if anyone else has a commercially available single package solution at this time. This could be called a fully loaded energy-harvesting chip, discussed long ago in an article "Energy-harvesting chips and the quest for everlasting life" posted by Erick O.

These specs are hard to bit and are needed for low power energy harvesting. MAX17710 1nA Standby IQBATT 625nA Linear Charging 1W Boost Charging Lithium Cell Undervoltage Protection Charger Overvoltage Shunt Protection 1.8V, 2.3V, or 3.3V LDO (150nA IQBATT)

Good move Maxim, you have a sight on a market that needs nurturing and have taken a step in the right direction. As a company (Maxim) we continue to see product that push the market versus taking a status quo position in power management or waiting for someone to make a move!

Hmmm... meeting those tight specifications may be challenging in an energy harvesting application. It may be premature to talk about using this technology for "autonomous, perpetually powered solutions for decades of use". I hope these don't prove to be like the early rechargeable batteries I used to buy: cost more than alkaline, discharged faster, lower voltage, and total life cycle cost was greater than what they replaced.

Tried for months to get real data from Thinergy on these batteries. Nothing provided. Seem you can't either overcharge or allow them to get discharged so if you leave them for any time without charging they will die. Maybe this Maxim part has a fix?

It may not last decades, but it is better than where we are today. Yes, those batteries don't last as long as they should, but it is still cheaper and better for the environment than using the not rechargables. We have to start somewhere.

Sounds a lot like something that Linear Tech did last year.
