FTM 25-iv development boards

This is the standard evaluation board for the Infineon PSOC™  Control C3 family of MCU’s.

Fast-switching gallium nitride (GaN) and silicon carbide (SiC) power components enable power-system designers to reduce the size of the magnetics in ac-dc and dc-dc converters, and to realize designs which achieve high power density.

The EVSPIN32G06Q1S3 board from STMicroelectronics is a complete three-phase inverter based on the STSPIN32G0601 controller, which integrates a three‑phase 600 V gate driver and an Arm^® Cortex^®-M0+-based STM32 microcontroller.

The power stage features STGD6M65DF2 IGBTs from ST, but can be populated with any IGBT or power MOSFET in a DPAK or powerFLAT 8×8 HV package.

The board has a three-shunt sensing topology, and supports a field-oriented control (FOC) algorithm, in either sensored or sensorless mode. This makes it especially suitable for driving permanent magnet synchronous motors (PMSMs).

 The evaluation board supports a wide input-voltage range, and includes a power supply stage with the ST VIPER06XS in flyback configuration.

The OPTIGA™ Trust M Shield from Infineon provides a convenient way to evaluate the OPTIGA Trust M family of discrete secure elements. 

It is supplied in a popular mikroBus format which makes it easy to integrate into prototype systems based on any microcontroller or microprocessor platform. The shield board can also be used with single-board computers when supported by the appropriate adapters. 

The OPTIGA Trust M Shield is compatible with the Infineon PSOC™ 62S2 Wi-Fi BT Pioneer Kit and OPTIGA Trust Adapter.

Features of the shield board include:

• Pre-provisioned TLS security certificates
• CC EAL 6+ certified hardware
• Qwiic compatible
• I2C interface with shielded connection
• Cryptographic toolbox
• Supports multiple cryptographic algorithms: ECC, RSA, AES, HMAC, HKDF, TLS PRF

The EVLSTGAP3S6S is a half-bridge evaluation board for evaluating the STGAP3S6S isolated single gate driver from STMicroelectronics.

The STGAP3S6S features a maximum 6 A current capability, rail-to-rail outputs, and optimized under-voltage lockout and desaturation protection thresholds for silicon carbide (SiC) MOSFETS. It is ideal for use in high-power industrial motor drivers.

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

Device protection features 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 hardware interlocking protection to avoid cross-conduction in case of controller malfunction.

The gate driver allows negative gate driving, and the onboard isolated dc-dc converters provide an optimized drive voltage for SiC MOSFETs.

The Nexperia NEVB-MCTRL-100 BLDC motor driver kit provides a full motor drive solution for 12 V to 48 V, three-phase brushless dc (BLDC) motors. 

The kit features PCBs designed for the Nexperia NextPower MOSFET family housed in an LFPAK56 package, and the modular design allows for different motor controllers, gate drivers, MOSFETs and motors to be used. In addition, each board provides convenient test points for power, motor drive, and sensing signals to aid with development and testing with the Nexperia LFPAK56 MOSFET family. 

The motor controller board is compatible with the Leonardo R3 and Nucleo development board form factors.

STMicroelectronics has implemented a simple and innovative ac-dc front-end circuit which enables the designer to perform inrush current limitation in any converter that has an input rectifier bridge topology.

The STEVAL-SCR002V1 is based on a control circuit made of one Z0110MN surface-mount triac and two STTH110A diodes. Two 800 V TN1605H-8T silicon-controlled rectifiers (SCRs) are used to bypass an inrush resistor. 

The evaluation board provides a compact and non-insulated high-voltage driver for a mains SCR. The drive circuit synchronizes the SCR gate signals with the ac line polarity, and powers the SCR gate directly from the mains. This operation does not generate reverse losses in the SCR.

Compared to electromechanical alternatives, this solid-state solution provides higher reliability, longer service lifetime, lower EMI, and faster response. This ST circuit is also compatible with inrush current limitation performed either in the NTC/PTC bypass mode or in microcontroller phase-control mode.

The STEVAL-SCR002V1 may be powered by an uninsulated power supply, or directly controlled by an MCU. It is suitable for applications with an rms current up to 4.3 A at 60°C, and is compatible with ac-dc converters with or without PFC operating in continuous conduction, critical conduction or discontinuous conduction modes.

The STEVAL-A6983CV1 and STEVAL-A6983NV1 from STMicroelectronics are evaluation boards for testing the performance of the A6983C and A6983N series automotive-grade synchronous monolithic step-down regulators. The A6983C regulators are optimized for low power consumption in light-load mode, and the A6983N are optimized for low-noise operation.  

The STEVAL-A6983CV1 and STEVAL-A6983NV1 feature a Power good open collector which monitors the feedback voltage. Pulse-by-pulse current sensing on both power elements provides for effective constant-current protection. Thermal shutdown prevents thermal run-away.
