Application schematic and pin description

The TSC102 high-side current sense amplifier features a 2.8 V to 30 V input common-mode

range that is independent of the supply voltage. The main advantage of this feature is that it

allows high-side current sensing at voltages much greater than the supply voltage (VCC).
