  • This important information is very well hidden! A hint in the data sheet (section Applications Information, paragraph HIGH-SIDE CURRENT SENSE WITH A HIGH-SIDE SWITCH) would have saved us from quite some time searching for the mistake in our circuit.

    Glad to have found the explanation now, anyway. Thanks.
