T1xy and T2xy correspond to the high-current rated load connectors. By default, the EVM is only populated with two of these connectors on the bidirectional, lowest gain variant (x = B and y = A). The IN+ (T1xy) and IN– (T2xy) inputs 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 gain and is presented at the VOUT test point (TP2xy). The acceptable load input maximum is 30 A for DC measurements. However, the load can be significantly higher for AC signals, and the load is bound by the safe operating area (SOA) described in the TMCS1108 data sheet.
