Features & Applications

The STEVAL-AETKT1V1 evaluation kit implements a bidirectional current sense amplifier consisting of a sense resistor placed either on the high side or the low side. The kit consists of a main board and a daughter board with TSC2011 high voltage, bidirectional, current sense amplifier providing a fixed gain of 60.

The TSC2011 device implements a thin film resistor for extremely precise gain and very high common-mode rejection ratio (CMRR) performance, even in high frequency ranges. The device can work with an input common mode voltage well beyond the power supply VCC range (2.7 V to 5.5 V), which is ideal for automotive and similar applications requiring reverse battery support without consequent damage. It also works with 48 V battery applications, as the device can support and measure the current on line at voltages up to 70 V, no additional protective components are required in that range. Moreover, the ability to fix the output common mode voltage means that the device can be either used as unidirectional or bidirectional current sensing amplifier.
 The main board in the kit can accommodate other daughter boards with TSC201x current sense amplifiers to allow testing and evaluation of different gain configurations.
