Application schematic and pin description

The TSC1031 high-side current sense amplifier can be used in either single- or dual-supply

mode. In the single-supply configuration, the TSC1031 features a wide 2.9 V to 70 V input

common-mode range totally independent of the supply voltage. In the dual-supply range,

the common-mode range is shifted by the value of the negative voltage applied on the Vcc-

pin. For instance, with Vcc+ = 5 V and Vcc- = -5 V, then the input common-mode range is

-2.1 V to 65 V.
