STMicroelectronics STEVAL-AETKT1V2

Overview

STEVAL-AETKT1V2 from STMicroelectronics is an evaluation kit for high-voltage, bidirectional current sense amplifiers, supporting TSC2010 (gain = 20), TSC2011 (gain = 60), and TSC2012 (gain = 100) ICs with ±200 µV max offset, -20 to 70 V common-mode range, and operation from -40°C to 125°C. It enables precision shunt-based current measurement in automotive motor control and industrial power tools.

For engineers reviewing the STEVAL-AETKT1V2 datasheet, STEVAL-AETKT1V2 pinout, STEVAL-AETKT1V2 application, or STEVAL-AETKT1V2 equivalent, this kit provides validated hardware platforms for evaluating high-side/low-side bidirectional sensing topologies, gain selection, output common-mode configuration, and thermal performance under real-world load conditions.

Technical Context

The kit integrates a main board (STEVAL-AET001V1B) and three daughter boards-STEVAL-AET002V1B (TSC2011), STEVAL-AET003V1B (TSC2010), and STEVAL-AET004V1B (TSC2012)-each implementing fixed-gain, high-CMRR current sensing using thin-film resistors. Each daughter board supports SO8/MiniSO8 footprint adaptation via MSO8-to-DIP8 interface.

All daughter boards feature independent shutdown (SHDN), reference voltage inputs (VREF1/VREF2), and configurable output common-mode voltage, enabling unidirectional or bidirectional current measurement without external level-shifting circuitry. Supply voltage range is 2.7–5.5 V with 20 µA quiescent current in shutdown mode.

FAQ

Does STEVAL-AETKT1V2 include all three TSC201x devices on one board?

No. The kit includes one main board (STEVAL-AET001V1B) and three separate daughter boards: STEVAL-AET002V1B (TSC2011), STEVAL-AET003V1B (TSC2010), and STEVAL-AET004V1B (TSC2012). Each daughter board hosts only its designated amplifier IC and corresponding passive network for that specific gain setting.

Can the output common-mode voltage be adjusted externally?

Yes. VREF1 and VREF2 pins on each daughter board allow independent setting of output common-mode voltage. This enables flexible interfacing with ADCs or microcontrollers operating at different reference voltages, supporting both unidirectional and bidirectional current sensing configurations without additional op-amp circuitry.

Is the main board sold separately?

No. The main board (STEVAL-AET001V1B) is not available for separate sale and is only supplied as part of the complete STEVAL-AETKT1V2 evaluation kit. It provides power regulation, header interfaces, and signal routing but contains no active current-sense ICs.

What package types do the TSC201x daughter boards support?

Each daughter board implements either SO8 or MiniSO8 footprint and includes an MSO8-to-DIP8 adapter section (J1) for breadboard prototyping. The physical layout matches the respective TSC201x IC's official package dimensions and pad spacing per ST's datasheet mechanical drawings.
