STMicroelectronics

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.

Renesas

The RTK-251-SinkCharger-RAA489118 from Renesas is a single-port reference design for implementing battery systems with from two to seven lithium-ion battery cells connected in series. It supports two modes: in one, power is supplied solely from the USB Type-C® port; in the other, it enables a power bank function in combination with a li-ion battery with a battery management system (BMS).

Due to losses in the cable, onboard charger, and board, the USB Power Delivery (PD) controller requires appropriate USB Type-C input levels from the USB Type-C source device to operate the battery system effectively. Switches on this evaluation board allow the selection of the number of batteries in series and the charging current.

The firmware for this evaluation board is generated using an instruction tool called VIDWriter.

Renesas

The RA8E1 Fast Prototyping Board from Renesas is an evaluation board for prototype development based on the high-performance, value-oriented RA8E1 microcontroller. 

It has a built-in SEGGER J-Link™ emulator circuit to enable developers to write and debug programs without additional tools. Sample software is available to demonstrate the functionality of the RA8E1 MCU, and for connecting the RA8E1 Fast Prototyping Board with various wireless or sensor modules.

Key features of the board include:

  • Native pin access through 1 x 20 and 2 x 50 male pin headers
  • 20-pin camera interface connector
  • MCU current measurement point 
  • Two user LEDs 
  • Power LED indicating availability of regulated power
  • Debug LED indicating the debug connection
  • One User button
  • One Reset button
  • Two Digilent Pmod™ connectors
  • Arduino UNO R3 connector

The NCD57252 evaluation driver board enables evaluation of the NCD57252, a high-current gate driver which can directly drive two independent IGBTs in any configuration. The driver provides 5 kVrmss of internal galvanic isolation from input to each output and functional isolation between the two output channels. 

STMicroelectronics

The STM32U083C-DK Discovery kit from STMicroelectronics is a complete demonstration and development platform for the STM32U083MCT6 microcontroller. It may be used as a reference design for application development before porting to the final product.

The full range of hardware features on the board helps the designer to evaluate all the MCU’s peripherals including the USB 2.0 interface, segment LCD controller, capacitive touch-sensing channels, and temperature sensor. 

ARDUINO Uno V3, mikroBUS™ and extension connectors provide for easy connection to extension shields or application-specific daughterboards.

The STM32U083C-DK Discovery kit does not require any separate probe as it has an integrated STLINK-V2EC debugger/programmer. The kit  is operated by plugging it into a PC through a standard USB Type-A or USB Type-C®-to-USB Type-C cable.

The board is supported by the STM32CubeU0 embedded software package.
