STMicroelectronics

The STEVAL-56G3MAI1 module enables easy evaluation of the VD56G3 1.5 Mpixel monochrome image sensor from STMicroelectronics. The module features a soldered sensor in a PLCC package, an M12 lens holder screwed to the board, and a removable lens. The module also has a flex cable to connect to a broad range of embedded processing platforms. 

The module is one of a family of modules for evaluating various products in the ST BrightSense image sensor portfolio. All share the same standard connector and pinout, to enable easy replacement of one image sensor with another in proof-of-concept designs. 

All of the image sensor modules are backed by a comprehensive set of enablement software, drivers and evaluation tools, including drivers for a Linux® operating system. The modules also support GUI software for evaluation when paired with the STEVAL-EVK-U0I1EVK evaluation board.

The EVALSTGAP2SICS half-bridge board from STMicroelectronics enables evaluation of the STGAP2SICS, an isolated single-channel gate driver for silicon carbide (SiC) MOSFETs. The STGAP2SiCS produces an output drive current of up to 4 A, and offers galvanic isolation of 6 kV. 

In the EVALSTGAP2SiCS board, the STGAP2SiCS drives a half-bridge power stage with a voltage rating of up to 1,200 V. The components are easy to access on the board and to modify.  

The board supports negative gate driving. Onboard isolated dc-dc converters supply the high- and low-side gate drivers, with maximum isolation of 5.2 kV. 

The configuration of the drive voltage can be easily selected from the following options:

  • +17 V/0 V
  • +17 V/-3 V
  • +19 V/0 V
  • +19 V/-3 V
Renesas

The MCK-RA8T1 evaluation kit by Renesas comprises several boards for easy testing of the RA8T1 series microcontrollers in brushless dc (BLDC) motor-control applications. The following items are included in the kit:

  • CPU board, based on the R7FA8T1AHECBD MCU
  • Communication board
  • Inverter board
  • BLDC motor
  • Cables, screws, and standoffs

When assembled, this kit enables designers to configure the motor-control system via a USB connection to a PC. It can control up to two BLDC motors by connecting two inverter boards to the main CPU board, which features two Pmod headers for connecting additional modules during development.

The complete assembly can be powered by a 12 V to 48 V dc supply via a dc jack or terminal block connection. Alternatively, it can be powered using a 5 V USB connection to the CPU board.

As well as the MOSFET-based motor control circuit, the inverter board features current detection circuits to measure the current in the 3-phase system. An over-current detection circuit is also present, but this does not protect the board or motor. Protection operations must be processed and controlled using the RA8T1 MCU on the CPU board.

The inverter board also features connectors for Hall sensor signal input and pins for encoder or inductive position sensor signal input. These can be used to support accurate motor positioning when developing an application.

The EVSPIN958 single brushed dc motor driver expansion board is an easy-to-use solution for testing the performance of the STSPIN958 5 A full-bridge driver from STMicroelectronics. It supports a voltage range from 5 V to 58 V with a phase current up to 5 A.

STMicroelectronics

The EVSPIN32G4 and EVSPIN32G4NH are demonstration boards based on the STSPIN32G4 SiP and STL110N10F7 power MOSFETs. The boards support three- or single-shunt configurations, and can run both sensorless and sensored control algorithms.

The integrated operational amplifiers for current sensing, the drain-source voltage sensing at each power MOSFET, and comparators for over-current protection make this a fully integrated solution for motor control.

Thanks to the integrated voltage regulators, both the gate driver and control logic supplies can be generated from the motor supply without dedicated circuitry. The board is intended to drive three-phase brushless dc (BLDC) motors in applications such as power tools, e-Bikes, fans, and home appliances.

A connector enables the EVSPIN32G4 to be interfaced with expansion boards, such as MEMS sensors or Bluetooth® transceivers. The on-board ST-LINK/V2 programmer speeds up and simplifies the debugging of microcontroller firmware.
