产品概要
描述
The STEVAL-AETKT4V1 evaluation kit implements bidirectional current sense amplifiers. It consists of a motherboard and three different daughter boards for different gain configurations.
The STEVAL-AET041V1B is a mother board, which can accept different daughter boards to use different gain configuration.
STEVAL-AET042V1B: daughter board with a TSC2020 mounted with a gain of 20.
STEVAL-AET043V1B: daughter board with a TSC2021 mounted with a gain of 50.
STEVAL-AET044V1B: daughter board with a TSC2022 mounted with a gain of 100.
The TSC202x family is a current sense amplifier specifically designed to accurately measure current by amplifying the voltage across a shunt resistor connected to its input. It features a zero-drift topology, allowing it to achieve a high CMRR of at least 100 dB and a low input-offset voltage of 200 µV at a common mode voltage of 12 V and over temperature.
Thanks to the use of thin film resistor, TSC202x offers an extremely precise gain and very high CMRR performance even in the high frequency range. Moreover, there is the possibility to fix the output common mode voltage allowing the TSC202x to be either used as a unidirectional or bidirectional current sensing amplifier.
TSC202x embedded a system to optimize the PWM rejection, allowing to reduce the effect of fast input common mode voltage variation on the output signal.
