Wanted: RF Reciever IC with "Sleep" ability
I'm in Automated Home technologies - I need to install a reciever unit (RF -
FCC approved freq.) which will "lay low" and not tax the snot out of batteries. For example: Your RC cars which you purchase from WalMart - use a chip that quickly eats the batteries up. Cell Phones are polling the stations constantly and tax the batteries up., I need an IC that will LAY LOW / SLEEP - perhaps look every 1 second for a signal and STARTUP at that point. My unit is a simple 4.5V DC operated motor that I wish to trigger RIGHT/LEFT perhaps only once / month! My unit is to be installed and the batteries would be a major pain to replace - would destroy sales of unit. Cell phones (I would think) should seek this kind of technology - that is, only "peek" once in a while for the data and sleep the remainder of the time. But perhaps, Cell Phones have much more "to do" than my simple application. I am simply "opening and closing" a small door with a small DC motor. But my issue is that all the RF Reciever IC's I've investigated are BUZY BUZY - They eat up a pair of 'AA' batteries in 1 Month with conservative circuitry - that unaccacceptable for my applicaction. If anyone knows of an RF Reciever IC that has this "sleep" ability built in - it would be RADICALLY appreciated !!!!! What about simple pager units??? Are they "charge me charge me charge me"??? Why aren''t the engineers considering the "look occasionally for data/signal" condition instead of constantly looking at the freq: which they are triggered at? Best Regards to all Walt |
