Hello,
I wander what would happen if flowing AC current in a uni-directional current sensors such as ACS715. Will the chip fry ? Will it block reverse current ? Or will it just give no output (ie 0V or alike) when current is flowing in the reverse direction ?
My intent is to use such a chip to build an electrical appliance usage sensor. This boils down to detect the presence of a current above a given threshold, without trying to measure it. The reason I want to use a DC current sensor in place of a AC one is to double the sensitivity (thanks to the fact that the output signal is originated at 0V and not at Vcc/2), and thus to allow a reliable detection of low currents.
I have carefully read the datasheets of both kinds of chips, but could not find any information about this question. So I would be grateful if somebody could provide my some clue.
Thanks in advance
Best regards.
