  • 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 50 V/V or 100 V/V by a selection pin.

    Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.
    The input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.9 to 70 V 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 360 μA and a virtually null input leakage current in standby mode, the power consumption in the applications is minimized.

    Key Features

    • Independent supply and input common-mode voltages
    • Wide common-mode operating range: 2.9 to 70 V in single-supply configuration -2.1 to 65 V in dual-supply configuration
    • Wide common-mode surviving range: -16 to 75 V (reversed battery and load-dump conditions)
    • Supply voltage range: 2.7 to 5.5 V in single supply configuration
    • Low current consumption: ICCmax = 360 μA
    • Pin selectable gain: 50 V/V or 100 V/V
    • Buffered output
    • EMI filtering
