I want to use LTC4020 in my project to charge a lead acid battery.
I found a problem and do not know how to solve it, if I turn it off during operation and charging the battery, then the voltage on Vout jumps to > 40 volts, my output capacitor exploded. Is this normal LTC4020 operation or do I have a problem?
I will try to help you with your problem.
Please advise input, output voltage range, battery chemistry and full-charge voltage. Attach a schematic according to the information below.
WATaylor Thanks for answering my question. I found an error in my project, I connected the Source and Drain Batt mosfet incorrectly, maybe the problem arose because of this. At the moment, I have not encountered this problem anymore.
Thanks Vladimir for this info.
