I need a charging circuit designed for a lead acid battery and solar panel. The solar panel puts out 5 Watts / 5VDC. The battery I need to charge is a sealed lead acid 4VDC 9AH. You can use the TI BQ24650 to charge the battery (see attached app note) and use MICREL linear voltage regulator MIC29302 (see attached) to supply power from the battery to my device that will be consuming the power. So, the circuit is roughly:
Solar Panel -> BQ24650 -> Lead Acid Battery
Lead Acid Battery -> MIC29302 -> My device that requires the output of the regulator.
Please create the schematic for me to review. Then, I will post another project for the PCB layout. I would invite you to bid on that next.
Thanks for looking at my project!
