#182082 - Raj should come back... Responding to: ???'s previous message |

when so, you usually end up with a worse, more expensive, and, sometimes, ARGH a "calibration requiring" design. As long as we do not know, what Raj is actually doing, we cannot say, what is worse and more expensive. These chips from LT are brilliant, of course. But they are built for Li-ion cells, not lead-acid cells Raj is using. So, only a chip offering the possibility of adjusting the undervoltage threshold would be helpful (LTC6801) for a simple undervoltage detection. But the LTC6801 does not provide an overvoltage detection for lead-acid cells. From my experience I would never again use a chip which is brought to the market by only one manufacturer. So, a circuit using standard components can be highly useful! Take into consideration, that not all people are living in the USA. Here in Germany availability of chips from the USA is big trouble from time to time. I remember many times when MAXIM chips, e.g., couldn't be shipped to Europe, but were available in the USA. We needed a contact man living in the USA to get out MAXIM chips... Kai Klaas |
