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 (V
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 (V
CC
).
