STMicroelectronics STEVAL-ISQ010V1

Overview

STEVAL-ISQ010V1 from STMicroelectronics is an evaluation board designed to demonstrate the TSC102 high-side current sense amplifier with integrated signal conditioning amplifier. It supports 2.8–30 V common-mode input range, ±2.3 mV input offset voltage over temperature, 20 V/V fixed gain, 4 kV HBM ESD protection on Vp/Vm pins, and operation from –40 °C to +125 °C. The board enables rapid validation of high-side current sensing in automotive battery monitoring and DC motor control systems.

For engineers reviewing the STEVAL-ISQ010V1 datasheet, STEVAL-ISQ010V1 pinout, STEVAL-ISQ010V1 application, or STEVAL-ISQ010V1 equivalent, this board provides a ready-to-use platform for evaluating TSC102 performance under real-world high-voltage transient conditions-including reversed battery (–16 V), load dump (60 V), and fast transient immunity-while verifying output signal conditioning flexibility via its fully accessible A1/A2/A3 amplifier terminals.

Technical Context

The STEVAL-ISQ010V1 implements the TSC102 in TSSOP8 package, interfacing directly with external shunt resistors to measure differential voltages up to ±20 mV while rejecting common-mode voltages from 2.8 V to 30 V independent of VCC. Its onboard layout isolates high-side sensing paths and provides test points for Vp, Vm, A1, A2, A3, and Out signals.

The board integrates decoupling capacitors, jumper-selectable gain configurations (including unity-gain buffer and adjustable gain via external R1/R2), and configurable overcurrent protection circuitry using the TSC102's dual-amplifier architecture. All critical analog nodes follow ST's high-precision current-sense layout guidelines to minimize parasitic coupling and thermal EMF errors.

FAQ

What is the primary function of the STEVAL-ISQ010V1 evaluation board?

The STEVAL-ISQ010V1 is a dedicated evaluation platform for the TSC102 high-side current sense amplifier. It provides a pre-layout, tested PCB with test points, jumpers, and supporting passive components to validate the device's performance-including common-mode rejection, offset stability, transient survivability, and signal conditioning flexibility-in real high-voltage systems like automotive battery monitors and motor drives.

Does the board support both TSSOP8 and SO8 versions of the TSC102?

No. The STEVAL-ISQ010V1 is specifically designed for the TSC102IPT (TSSOP8) variant. Its footprint, thermal relief, and signal routing are optimized for the 3 mm × 4.4 mm TSSOP8 package. The SO8 version (TSC102IDT) requires a different board layout due to larger dimensions (4.9 mm × 6.0 mm) and distinct thermal and parasitic characteristics.

Can the signal conditioning amplifier on the board be configured for filtering or overcurrent detection?

Yes. The board exposes A1 (current sense output), A2 (non-inverting input), and A3 (inverting input) terminals, enabling users to implement first- or second-order low-pass filters (via R/C networks), adjustable gain stages, or comparator-based overcurrent protection-as shown in Figures 22–26 of the TSC102 datasheet. Jumper options allow quick reconfiguration between buffer, gain >20, gain <20, and protection modes.

What transient protection features does the STEVAL-ISQ010V1 demonstrate?

The board validates the TSC102's inherent ruggedness: it withstands –16 V (reversed battery), +60 V (load dump), and 4 kV HBM ESD on Vp/Vm pins without external clamping. Layout practices-including short high-current traces, ground plane isolation, and guarded sense lines-preserve these specifications during system-level testing, making it suitable for ISO 7637-2 pulse validation.
