TSC2010, TSC2011, TSC2012
Description
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.

1. All voltage values, except the differential voltage are with respect to the network ground terminal.
2. Input voltage can go beyond supply voltage but input current must be limited. Using a serial resistor with the input is highly
recommended in that case.
