The EVLSTGAP3SXS-H is a half-bridge evaluation board designed to evaluate the STGAP3SXS isolated single gate driver for SiC MOSFETs.

The STGAP3SXS offers 10A current capability, rail-to-rail outputs and optimized UVLO and desaturation protection thresholds for SiC MOSFETS. This makes the STGAP3SXS optimal for high-power motor drivers in industrial applications.

The gate driver has a single output pin and a driver line for an external Miller clamp N-channel MOSFET, which optimizes the suppression of positive and negative gate spikes during fast commutations in half-bridge topologies.

The board is supplied by the 5V VAUX connection, which feeds the isolated dc-dc converters for the low-side and high-side driving sections. The gate drivers can be directly supplied by VAUX if a 5V MCU is used, or by the onboard linear regulator if a 3.3V MCU is used. The PWM and Reset inputs can be easily controlled through dedicated connectors while diagnostic outputs are connected to an onboard LED.

Device protection features for desaturation, soft turn-off, and Miller clamp are connected to the recommended network on the board and can be easily evaluated through the board test points.

Dual input pins allow the selection of signal polarity control and implementation of HW interlocking protection to avoid cross-conduction in case of controller malfunction.

The STGAP3SXS allows the implementation of negative gate driving, and the onboard isolated dc-dc converters allow working with optimized driving voltage for SiC MOSFETs.

The EVLSTGAP3SXS-H board allows evaluating all of the STGAP3SXS features while operating with a bus voltage up to 520V. It is possible to increase the bus voltage up to 1200V by replacing the two SiC MOSFETs with appropriate devices in a HiP247-4 package and the C4 capacitance if needed.

The B-G474E-DPOW1 Discovery Kit is a complete digital power development platform built around an STM32G4 MCU. It features an onboard buck-boost converter (with selectable internal or external input and resistive load bank) and a high-brightness RGB LED, allowing developers to evaluate DC-DC conversion and LED lighting control designs. A Class-D audio amplifier circuit is also included to demonstrate digital power in audio applications. The kit provides rich user interface and connectivity, including four user LEDs, a 4-direction joystick, a USB Type-C™ port supporting USB Power Delivery 3.0, a Micro-USB port (for ST-Link), and extension headers for additional peripherals.

This 3‑phase inverter board provides a complete motor drive for prototyping high-voltage BLDC/PMSM control. It features a 650V-rated power stage capable of about 300W output and accepts between 50 and 400V dc bus input. An onboard flyback converter generates the necessary 15V and 3.3V supplies for the gate driver and MCU. The board uses single-shunt current sensing and supports both sensorless and sensored FOC or six-step control algorithms out of the box. Standard STM32 debugging and programming tools are supported via an external SWD connector on board (STLINK), and headers are provided for motor feedback. This evaluation kit helps to evaluate the STSPIN32G0602Q in real-world motor control applications.

The STEVAL-MKI243A is an adapter board designed to facilitate the evaluation of the ASM330LHHXG1 6-axis IMU (inertial measurement unit) in automotive applications. The board offers an effective solution for fast system prototyping and device evaluation directly within the user’s own application. 

The STEVAL-MKI243A can be plugged into a standard DIL24 socket. The adapter provides the complete ASM330LHHXG1 pinout and comes ready to use with the required decoupling capacitors on the VDD power supply line. 

This adapter is supported by the STEVAL-MKI109D evaluation platform, which includes a high-performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable MEMS Studio graphical user interface or dedicated software routines for customized applications.

The STEVAL-3601CV1 demonstrates a smart converter design able to deliver up to 1A output current from a 3.3 to 36V input, with a 5V output voltage. The board features the DCP3601 miniaturized synchronous step-down converter, which implements enhanced peak current control and advanced design circuitry to minimize quiescent current. The board demonstrates how highly efficient conversion can be achieved with just the DCP3601, an inductor, two small capacitors, and two resistors.

 

The board highlights key application benefits made possible by the DCP3601, including high efficiency and small PCB size, and is ideal for power conversion solutions in major appliances, smart metering, industrial 24V BUS conversion and general-purpose wide power supplies.
