The EVSPIN32G4-DUAL is a demonstration board based on the STSPIN32G4 and STDRIVE101 for applications using two three-phase brushless motors.
The STSPIN32G4 is a system in package integrating in a 9×9 mm 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 4×4 VFQPN package featuring 600 mA current capability and embedded protections.
The two power stages based on the STL110N10F7 power MOSFETs can simultaneously operate up to 10 Arm output current and 74 V supply, providing dedicated monitoring for temperature and bus voltage, 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 both the gate driver and control logic supplies can be generated starting from the motors’ supplies without dedicated circuitry.
Predisposition for CAN bus enables the EVSPIN32G4-DUAL to easily connect with master or slave modules and build complex motion control systems.
