New low- and high-side bidirectional current sense amplifiers feature very low drift

TSC21x series from STMicroelectronics provides a wide range of gain options to enable designers to find the right fit for their industrial or automotive application.

The TSC21x series from STMicroelectronics are bidirectional current sense amplifiers for use with a shunt resistor to measure current with a high degree of precision and accuracy. Based on a zero-drift architecture, the amplifiers’ performance is very stable over the operating-temperature range of -40°C to 125°C. 

The TSC21x current sense amplifiers operate over a wide supply-voltage range of 2.7 V to 26 V and offer high tolerance of ESD, making them ideal for industrial and automotive applications. 

The amplifiers can perform high- or low-side current sensing, and are also suitable for other functions such as over-current protection, current monitoring and feedback loops.

There are six amplifiers in the TSC21x series. The amplifier gain of the TSC210 is 200 V/V, for the TSC211 the gain is 500 V/V, 1,000 V/V for the TSC212, 50 V/V for the TSC213, 100 V/V for the TSC214, and 75 V/V for the TSC215. 

The TSC21x amplifiers are supplied in either a QFN10 package measuring 1.8 mm x 1.4 mm, or an SC70-6 package.
