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 AEK-POW-BMSCC is a compact battery management system module based on the L9963E, optimized for easy mounting in battery packs. It can be used in a centralized daisy-chain as an intermediate node, where the first node is an AEK-POW-BMSCCTX. As an intermediate node, the AEK-POW-BMSCC can be part of a chain of up to 31 BMS nodes.

Each module monitors between 4 and 14 cells and can serve as an intermediate node in a daisy chain of up to 31 BMS nodes. The board provides voltage, current, and temperature sensing for each cell, enabling precise State-of-Charge estimation and cell balancing across the pack. Part of ST’s AutoDevKit ecosystem, the AEK-POW-BMSCC allows engineers to quickly prototype scalable, high-voltage battery management solutions with support for functional safety and real-time monitoring.

The STM32MP215F-DK Discovery Kit is a development platform for the STM32MP215 series. It features the STM32MP215DAN3 MPU, ST STPMIC2L power management, and 2GB of LPDDR4 DRAM, along with Gigabit Ethernet, USB-C, microSD, an LCD-TFT display connector, and a dual-lane MIPI CSI-2 camera connector. The board ships with the ST OpenSTLinux distribution on the A35 cores and STM32CubeMP2 firmware examples on the M33, enabling rapid prototyping and evaluation of industrial and vision-based applications.

Power Integrations

The RDR-1016 reference design board from Power Integrations implements a flyback converter which provides a dual isolated output voltage of 12V at 2A, and 5V at 500mA, from a wide input-voltage range of 85V to 265V ac. The power supply is based on the TNY5073K flyback converter, a member of the TinySwitch-5 family of ICs. 

The board achieves peak efficiency of at least 87% at full load with a 230V ac input. Average efficiency across the load range is at least 85%. 

The RDR-1016 conforms to the requirements of the CISPR22B/EN55022B standards for conducted EMI emissions. It is specified for operation at an ambient-temperature range of 0°C to 40°C with free-air convection cooling.
