STMicroelectronics STEVAL-AETKT2V1

Overview

STEVAL-AETKT2V1 from STMicroelectronics is an evaluation kit for high-precision bidirectional current sense amplifiers based on the TSC210 and TSC213 zero-drift ICs, supporting both high-side and low-side shunt placement, ±35 µV offset voltage, 0.1 µV/°C drift, and gain configurations from 50 V/V to 1000 V/V, used in electro-mobility battery monitoring and industrial motor control.

For engineers reviewing the STEVAL-AETKT2V1 datasheet, STEVAL-AETKT2V1 pinout, STEVAL-AETKT2V1 application, or STEVAL-AETKT2V1 equivalent, this kit enables rapid validation of bidirectional current sensing accuracy, CMRR performance >120 dB (via thin-film resistors), output common-mode voltage programmability, and thermal stability across –40°C to +125°C operation.

Technical Context

The kit integrates two daughter boards-STEVAL-AET012V1B (TSC213) and STEVAL-AET013V1B (TSC210)-each with fixed-gain configurations and DIP6 or SC70-6/QFN10 footprints, enabling direct comparison of 50 V/V vs. 1000 V/V gain paths under identical layout and supply conditions (2.7–26 V).

It implements reference-controlled output common-mode voltage via dedicated REF pins, supports unidirectional/bidirectional sensing through external VREF routing (e.g., TS431 adjustable reference), and includes SMA4F18A TVS diodes for input overvoltage protection up to ±18 V on sense inputs.

FAQ

What is the purpose of the REF pin on the TSC21x devices included in this kit?

The REF pin sets the output common-mode voltage, allowing the amplifier to interface directly with ADCs or controllers operating at different reference levels. In the STEVAL-AETKT2V1, it is routed to a TS431 adjustable shunt reference, enabling user-defined output bias from 0.5 V to VCC – 0.5 V for unidirectional or bidirectional sensing modes.

Can the STEVAL-AETKT2V1 be used for high-side current sensing in a 48 V system?

No - the TSC21x ICs support up to 26 V input common-mode voltage, and the kit's TVS diodes are rated for ±18 V clamping. For 48 V systems, external level-shifting or higher-voltage sense amplifiers (e.g., TSC2010) are required; this kit is validated only for ≤26 V rail applications.

How do the two daughter boards differ electrically?

The STEVAL-AET012V1B uses TSC213 (50 V/V gain, SC70-6 package), optimized for high-current, low-Vsense applications (e.g., 100 A with 2 mΩ shunt). The STEVAL-AET013V1B uses TSC210 (1000 V/V gain, QFN10 1.8×1.4 mm), suited for low-current, high-accuracy use cases (e.g., 1 A with 10 mΩ shunt), with distinct PCB layouts and decoupling networks.

Is the motherboard (STEVAL-AET011V1B) available for separate purchase?

No - the main board STEVAL-AET011V1B is not offered as a standalone orderable part. It is exclusively supplied as part of the complete STEVAL-AETKT2V1 kit, which includes both daughter boards and all necessary jumpers, connectors, and documentation (DB4471 data brief).
