Summary of SC2012 – HIGH VOLTAGE, PRECISION, BIDIRECTIONAL CURRENT SENSE AMPLIFIER
The TSC2010, TSC2011, and TSC2012 are precision bidirectional current-sense amplifiers that measure shunt voltages across a wide common-mode range (−20 to +70 V) independent of supply. They come in gains of 20, 60, and 100 V/V respectively, can detect very low full-scale drop voltages (~10 mV), and serve for precision current measurement, overcurrent protection, monitoring, and feedback. They operate from 2.7 to 5.5 V supply and across −40 to 125 °C, with low offset voltage (±200 µV max).
Parts used in the TSC2010/TSC2011/TSC2012 project:
- TSC2010 current sense amplifier (20 V/V)
- TSC2011 current sense amplifier (60 V/V)
- TSC2012 current sense amplifier (100 V/V)
- Shunt resistor for current sensing
- Supply voltage source (2.7 to 5.5 V)
- PCB or prototyping board
- Input common-mode voltage source (range −20 to +70 V)
- Passive components for filtering and stability (e.g., capacitors, resistors)
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.
