The input connectors labeled IN+_x and IN-_x correspond to the high-current rated load connectors supplied with the EVM. By default, the EVM is only populated with two of these connectors on the lowest sensitivity variant (A1, B1, or C1). These components are screwed to the board to make contact, and can be easily moved to the desired sensitivity option for test purposes. The fused lead frame inputs (pins 1 and 2 of the unit under test) accept a load that is converted to a magnetic field sensed by a Hall element that produces a voltage. This voltage is amplified by the selected device sensitivity and is presented at the VOUT test point. The acceptable load input maximum for the included connectors is 90A for DC measurements. However, the continuous allowable load is bounded by the safe operating area (SOA) described in the TMCS1127 data sheet.
