TSC101 - High Side Current Sense Amplifier

Description

The TSC101 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage.

The gain is internally fixed.

Wide input common-mode voltage range, low quiescent current, and tiny SOT23 packaging enable use in a wide variety of applications.

Features

  • Independent supply and input common-mode voltages.
  • Wide common-mode operating range: 2.8 to 30 V.
  • Wide common-mode surviving range: -0.3 to 60 V (load-dump).
  • Wide supply voltage range: 4 to 24 V.
  • Low current consumption: ICC max = 300 µA.
  • Internally fixed gain: 20 V/V, 50 V/V or 100 V/V.
  • Buffered output.
