STMicroelectronics — TSC2010, TSC2011, TSC2012 Current Sense Amplifiers

The TSC2010, TSC2011, and TSC2012 from STMicroelectronics are bi-directional current sense amplifiers for use with a shunt resistor to measure current with a high degree of precision and accuracy.

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.

The devices operate over a wide range of common-mode voltages from -20V to +70V, regardless of the supply voltage. The amplifiers are able to sense voltage drops as low as 10mV full-scale. The amplifier gain of the TSC2010 is 20V/V, for the TSC2011 the gain is 60V/V, and 100V/V for the TSC2012.

Maximum offset voltage is just ±200μV. The TSC201x parts are supplied in an SO8 or Mini-SO8 package.
