The datasheet for the ISL83204A full-bridge driver chip documents "low sense" pins that connect to the source of the bottom N-channel MOSFETs. As those are typically connected to ground, what is the function of these pins?
The data sheet does not mention these pins, except briefly as follows: Absolute max: +/- 2V compared to GND. Normal operation: +/- 1V compared to GND.
There's a diagram that shows "optional" resistors below the ALS and BLS pins, which look like current sense resistors, but there's no mention of whether this chip has current sense, over-current shut-off, or anything like that.
