STMicroelectronics EVSPIN32G4-DUAL Demonstration Board is based on the STSPIN32G4 and STDRIVE101 for applications using two three-phase brushless motors. The STSPIN32G4 is a system in package integrating into a 9mm x 9mm VFQFPN package, a triple high-performance half-bridge gate driver with a rich set of programmable features and one mixed signal STM32G431 microcontroller. The STDRIVE101 is a triple half-bridge gate driver in a compact 4mm x 4mm VFQPN package featuring 600mA current capability and embedded protections.
Based on the STL110N10F7 power, the two power stages MOSFETs can simultaneously operate up to 10Arm output current and 74V supply. This feature provides dedicated temperature and bus voltage monitoring, drain-source voltage sensing of power MOSFETs, and overcurrent protection. The board allows sensor-less operation with single shunt current sensing, taking advantage of operational amplifiers inside STSPIN32G4 as well as sensor-based control algorithms thanks to dedicated inputs for each motor among Hall sensors, quadrature encoder or absolute encoder with SSI communication interface.
Thanks to the integrated voltage regulators, the gate driver and control logic supplies can be generated starting from the motors’ supplies without dedicated circuitry. Predisposition for the CAN bus enables the STMicroelectronics EVSPIN32G4-DUAL to easily connect with master or slave modules and build complex motion control systems.
