Looking for a symbol/model... for the SI labs 4736 FM/AM/WB reciever chip. Just a little background. I have a somewhat complicated device I am trying to make for a 5 day 4 night seakayaking/camping trip on Lake Superior, and for future long hikes/trips/expeditions in upwards of a week or two.
I have some basic electrical experience, am good with computers, am able to research, am an "automotive technician", so I do not think it is beyond my abilities. Just a lot of work and learning to do. I was doing some research into laying out this project and stumbled upon the 4736 and would love to implement it. I have found a library/model for the MAX 712 NiMH charging regulator chip and have started to implement it. I have searched for and found this KiCad program and am finding it very useful. I would not feel comfortable about creating my own model/library with rules for the Si4736 and am wondering if anyone would be able to easily do this or point me into the correct direction to find one made already. I've spent a lot of the day on Si's site, have found some library's with some chips but not this one. A rough description of the device being dreamed up. CSI Solar Charger Model CS5Q-5D -Max Power 5W -Voltage at max power 18.5V -Current at max power 275mA Through a Max 712 or 713 NiCD/NiMH smart charge IC. Is going to charge an internal 10 cell bank of NiMH AA batteries. -Duracell 2650mAh, 1.2V, (standard charge 270mA for 16 hours.) Will also charge an external 4x AA NiMH and 3x AAA NiMH (1000mAh) on a seperate charge controller. (for the 2 LED lanterns and LED headlamp) Will have a common 12V auto car power supply jack for charging various 12V items using their , cell phone, GPS, etc..... I have portable external speakers with it's own 6v (4x AAA) power supply that now has it's power supply removed and will be powered from the internal battery bank. Was also looking at MAX's site and found a 2.1 audio circuit (two mid/tweets and a 9 watt subwoofer design) but might be a bit overkill for this. I will hack an Ipod cable to fully integrate Ipod audio to the amp'd speakers and charge the Ipod at the same time. I would very much like to switch the audio and incorporate this Si 4736 into the design. It would be great to have weatherband radio incorporated into this device. Basically an all in one renewable power source and entertainment unit for the stormy days/nights staying in the tent watching movies with weather radio and maybe alert???. Thanks in advance to anyone that can help or has any ideas, Greg If you would like to follow along with the project or are yourself interested, send me an email and perhaps we could brainstorm together.
