TCA 965 battery charger I think designed by Mark Kelly can't figure it out.

tca 965 based board. Who can tell me how to wire up?

I think this board was once designed by Mark Kelly for charging a 12V battery for his turntable controller.

But I don't have the schematic. And it seems a waste to throw it away. Might use it for a little boombox if I can get it charge my 12V SLA battery.

I can't decipher KG, CA, KR AND V1. And how to connect a battery to that. I also think I might have soldered in diodes instead of LED's but I just don't know.

Here are the pics. The example is just that. An example. It seems to me that the board I have is designed to just shut the charging off instead of giving the status via leds.

This IC cannot charge a battery without external components.

Search for TCA965 schematic in http://www.google.co.in/imghp?hl=en&tab=wi

Hallo Gajanan,

I know it cannot fuction without external components. 🙂

Just that I want to find out how the the pcb I have should be hooked up.

Kind regards,
Bas

Schematic is in google image search. I didn't post it for obvious reasons.

There are plenty of schematics.

But none resemble the one I have on my pcb. I'm looking for the schematic that goes with the board. Since I want to know if I soldered in the right components and I want to find out what the texts KG, CA, KR AND V1 mean.
