Description

The TSC2010H, TSC2011H and TSC2012H 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 20 V/V for TSC2010H, 60 V/V for TSC2011H

and 100 V/V for TSC2012H.

They are able to sense very low drop voltages as low as 10 mV full scale minimizing

the measurement error.

The TSC2010H, TSC2011H and TSC2012H 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 150 °C.
