STMicroelectronics' precision bidirectional current sense amplifiers can sense the current thanks to a shunt resistor

     STMicroelectronics' TSC2011, TSC2012, and TSC2010 are precision bidirectional current sense amplifiers that can sense the current thanks to a shunt resistor over a wide range of common mode voltages from -20 V to +70 V, no matter what the supply voltage is. It is available with an amplifier gain of 60 V/V for the TSC2011, 100 V/V for the TSC2012, and 20 V/V for the TSC2010, and able to sense very low drop voltages, as low as 10 mV full scale, minimizing the measurement error.

     The TSC2011, TSC2012, and TSC2010 can also be used in other functions such as precision current measurement, overcurrent protection, current monitoring, and feedback loops. These devices fully operate over the broad supply voltage range from 2.7 V to 5.5 V and industrial temperature range from -40°C to +150°C.
