Hello fellow Polulu designers,
My name is Bastian, and i have a following question about a ACS709. I want to measure about 40-45 amps of current and this can be done by the ACS709 And run it for lets say 8 Weeks, with a powerload of a Motor that runs at 40V at 40A. This all is driven by a big PB(Pumblum/Lead) battery (like the one you have in a old car).
The thing is (what i have read so far ) that the ACS709 is tested for 1000 secs at a Thermalresistance about 22C/W, at 30amps DC. Would it be wise to put a Big Heatsink on it, or like a Fan?
because of the Thermal Fatigue?
