TSC1031IYPT

The TSC1031IYPT is a high-voltage high-side Current Sense Amplifier for use with photovoltaic systems. The TSC1031 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The TSC1031’s dedicated schematic eases the implementation of EMI filtering in harsh environments. The gain is adjustable to 50V/V or 100V/V by a selection pin. The input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.9 to 70V in the single supply configuration or be offset by an adjustable voltage supplied on the Vcc- pin in the dual supply configuration. With a current consumption lower than 360µA and a virtually null input leakage current in standby mode, the power consumption in the applications is minimized.
