STMicroelectronics — TSC21x Series Current Sense Amplifiers

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.
