Sukhbinder Posted December 2, 2005 Report Share Posted December 2, 2005 hi guys, i just opened up a uniross photosprint battery charger which has 2 timer settings of 6 & 9 hrs. i found that they used a CD4060 for the timing. The CD4060 is a 14 stage ripple counter. Can any one suggest any circuit for a timer using this IC. I'm planning to make my own battery charger for NiCd and NiMh cells as i have quite a lot a lying around my home. i found the this charger quite impressive as it automatically cuts off the charging after the time duration and puts the cells to trickle charging. It has a dual led indicator which indicated red for charging and green for trickle charging. it supports 1-4 AAA or AA batteries or 2 9V batteries. If any one has a circuit for such type of chargers please tell me.thanx ;) Quote Link to comment Share on other sites More sharing options...
ante Posted December 2, 2005 Report Share Posted December 2, 2005 Hi Sukhbinder,Are you sure you want to charge NiCd and NiMh cell with a “timer”? These cells require a more sophisticated charge method to be optimized. The circuit required is not very complicated if you use this IC: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/1666/ln/en Quote Link to comment Share on other sites More sharing options...
Sukhbinder Posted December 5, 2005 Author Report Share Posted December 5, 2005 Thanks Ante for your suggestion but could u provide me with a simpler solution using conventional easily available components. the problem is that i live in New Delhi INDIA and the maxim IC is not available here easily. we have mail order firms like RS components here but they charge a lot. If u don't have a circuit in mind, could u just tell me how to use the C4060 as a timer. i'll take care of the constant current charging and voltage cutoff.thanks again Quote Link to comment Share on other sites More sharing options...
