While taking my BOM to Mouser to plan a parts order, I found that one of my preferred board mount current sensors, the Tamura L18P030S05R isn’t currently available in low quantities. Fortunately, there is an equivalent hall effect type current sensor that comes in a smaller, cheaper smd component, the Broadcom ACHS-7123. I prefer this technology over shunt type current sensors, as I think that they are, overall, cheaper, more accurate, and smaller, and this “new to me” Broadcom chip is a fine example of that.
