STMicroelectronics TSC2010/TSC2011/TSC2012
TSC2010/TSC2011/TSC2012 - High voltage, precision, bidirectional current sense amplifiers
The TSC2010, TSC2011 and TSC2012 are precision bidirectional current sense amplifiers. They can sense the current thanks to a shunt resistor over a wide range of common mode voltages, from - 20 to + 70 V, whatever the supply voltage is. They are available with an amplifier gain of 20V/V for TSC2010, 60 V/V for TSC2011 and 100 V/V for TSC2012.
They are able to sense very low drop voltages as low as 10 mV full scale minimizing the measurement error. The TSC2010, TSC2011 and TSC2012 can also be used in other functions such as: precision current measurement, overcurrent protection, current monitoring, and feedback loops.
This device fully operates over the broad supply voltage range from 2.7 to 5.5 V and over the industrial temperature range from -40 to 125 °C.

STEVAL-AETKT1V2 - Evaluation kit for high voltage bidirectional current sense amplifier
The STEVAL-AETKT1V2 evaluation kit represents a bidirectional current sense amplifier with high side or low side sense resistor. The kit consists of a main board and individual daughter boards for the TSC2011, TSC2010 and TSC2012 high voltage, bidirectional, current sense amplifier ICs, which provide a a fixed gain of 60, 20 or 100, respectively. The thin film resistor on the TSC201x devices ensure extremely precise gain and very high common-mode rejection ratio (CMRR) performance, even in high frequency ranges. They accurately measure current by amplifying the voltage (VSENSE) across a shunt resistor connected to the input. Moreover, the ability to fix the output common mode voltage means that the device can be either used as unidirectional or bidirectional current sensing amplifier.
