STMicroelectronics | STEVAL-ISQ007V1

The STEVAL-ISQ007V1 demonstration board is specifically designed for the TSC101 integrated circuit. The TSC101 measures a very small voltage drop on a high-side shunt resistor, and, using an internally fixed gain, amplifies the difference into a ground-referenced output voltage; the
amplification gain is internally fixed.

Input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.8 V to 30 V in operating conditions, and upto 60 V in absolute maximum ratings. The supply voltage can range from 4 V to 24 V. Current consumption of less than 300 μA over the temperature range and low input bias current (less than 8 μA in standard conditions, a few 100 nA if VCC isn't supplied) are particularly interesting to save power in the application.

Features :

• Low current consumption: ICC max is 300 μA
• Internally fixed gain:
• 20 V/V (TSC101A)
• 50 V/V (TSC101B)
• 100 V/V (TSC101C)
• Buffered output
