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

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.
