STSPIN32G4 3-Phase Motor Driver Power MOSFET Embedded STM32G4 MCU
The STSPIN32G4 is an extremely integrated and flexible motor controller for driving 3-phase brushless motors, helping designers to choose the most suitable driving mode and reduce PCB area and overall Bill Of Materials.
It embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 1 A (sink and source). Three bootstrap diodes are embedded as well. The high- and low-side switches of the same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function. An additional protection feature is represented by hardware VDS monitoring circuitry that constantly monitors each of the six external MOSFETs and in case an overvoltage is detected across one of them, switches off all gate driver outputs. The overvoltage threshold is set through a dedicated SCREF pin.
The device is fully self-supplied thanks to an integrated flexible power management structure able to generate all required supplies starting from the motor supply voltage, VM; the only one to be provided from outside. An embedded programmable buck regulator, with embedded power MOSFET, generates the supply voltage for the gate drivers starting from the motor supply voltage VM. Four different VCC output values can be selected through a dedicated configuration register, 8 V (default value), 10 V, 12 V and 15 V.
The STSPIN32G4 also features the full set of protections and an extended temperature range (-40°C to +125°C), guaranteeing stable operation even in the most demanding industrial applications. Both SWD and JTAG interfaces are provided for microcontroller firmware programming and debugging. Finally, with an additional external three-phase driver (such as the STDRIVE101) two independent 3-phase BLDC motors can be efficiently driven from the STSPIN32G4,offering an unprecedented BOM saving and application optimization.
