ST STEVAL-ISQ010V1 High-side Current-Sense Amplifier Demonstration Board Based on the TSC102 User Guide
Summary
This high-side current-sense amplifier demonstration board is engineered for accurate measurement of small voltage drops across shunt resistors using the TSC102 device. It provides robust signal conditioning by amplifying the measured difference into a ground-referenced output, featuring independent and wide-ranging common-mode input voltages (2.8 V to 30 V). Ideal for electrical engineers and developers requiring highly stable, low-power current monitoring solutions that handle extreme supply variations while maintaining precise performance.

Ro HS compliant
Description The STEVAL-ISQ010V1 demonstration board is specifically designed for the TSC102 device. The TSC102 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. The device is housed in a tiny TSSOP8 package. Input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.8 V to 30 V during operation. Under absolute maximum rating conditions, the Vp and Vm pins can sustain as much as 60 V to handle events like load-dump conditions, and as low as -16 V to deal with reverse battery conditions. The supply voltage can range from 3.5 V to 5.5 V, therefore the TSC102 can be supplied by the same voltage regulator used for digital circuits. Current consumption is less than 450 µA over the temperature range, and low input bias current is less than 7 µA in standard conditions.
