STMicroelectronics | TSC103IDT

The TSC103IDT measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The gain is adjustable to four different values from 20 V/V up to 100 V/V by two selection pins. Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.

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: ICC max = 360 μA
• Pin selectable gain: 20 V/V, 25 V/V, 50 V/V or 100 V/V
• Buffered output

Applications:

• Automotive current monitoring
• DC motor control
• Photovoltaic systems
• Battery chargers
• Precision current sources
• Current monitoring of notebook computers
• Uninterruptible power supplies
