This saves developers from having to use external GPIO pins to control a gate driver, while also avoiding the need for pc board space to run traces to a separate IC. GPIOs PA8 – PA10 are used for the gate driver’s high side inputs, while GPIOs PB13 – 15 are used for the gate driver’s low side inputs. GPIO PA11 is used to enable the gate driver, and GPIO PB12 is used to detect if there is a fault with the bridge.

Notice that internal to the IC, the STM32F031 microcontroller is connected to the gate driver through several GPIO lines that are internal to the package. The primary difference between the two is that the 0601 supports gate drive currents up to 0.35 amperes (A), while the 0602 can support gate drive currents up to 1.0 A. The STM32F060x currently includes two parts in the family, the STSPIN32F0601 and the STSPIN32F0602. The built-in microcontroller operates at 48 megahertz (MHz) and includes 32 kilobytes (Kbytes) of flash with 4 Kbytes of RAM, which is perfect for implementing field-oriented control (FOC). Integrated high-voltage bootstrap diodes.A comparator with an advanced smart shutdown (smartSD) function that ensures fast and effective protection against overload and overcurrent.

#Bldc motor driver controller series#
The series provides some very interesting features and protections. Each half-bridge can be used to drive a MOSFET or IGBT on each phase of a brushless DC (BLDC) motor.įigure 1: The STM32F060x integrates an STM32F031 Arm Cortex-M0 with a 600 volt triple half-bridge gate driver to save cost, pc board space, and package pins. This class is represented by the STMicroelectronics STSPIN32F060x SiP series of components that embeds an STM32F031圆x7 Arm® Cortex®-M0 microcontroller with a 600 volt triple half-bridge gate driver (Figure 1). This is where a new class of integrated microcontrollers and bridge circuits is simplifying motor control applications, while simultaneously decreasing BOM costs and minimizing pc board surface area.

The challenge with an external bridge driver IC in today’s development cycle is that they add additional cost and complexity and use up precious pc board space, not to mention input and output (I/O) signals on the microcontroller that might otherwise be used for something else. The microcontroller often also communicates with the motor drive IC through either an I 2C or SPI bus to enable custom features and functionalities, or it may use a half dozen or so discrete GPIO signals to control the bridge’s behavior. Typically, the microcontroller sends pulse width modulated (PWM) signals to the motor drive IC, which carefully monitors these signals along with the output current and voltage that are generated at the motor controller’s output, to drive the MOSFETs. In a traditional motor controller design, a developer will usually have a section of the pc board that is dedicated to all three blocks.

In order to successfully drive a 3-phase motor, there are several hardware blocks that must be built into the design:

This article will introduce STMicroelectronics’ STSPIN32F32F060x family of system-in-package (SiP) 3-phase motor controllers with a built-in microcontroller, and show how they can be used to achieve these design, cost, and time-to-market market challenges. With designers facing an increasing demand for lower BOM costs, higher efficiency and smaller footprint electronics, as well as greater flexibility and faster time to market, a higher degree of integration and ease of use is needed. However, motor electronics are traditionally heavy, bulky, inefficient, and difficult to work with due to the high drive voltages that are involved. The use of motors is steadily increasing in applications such as automobiles, robotics, industrial control and aerial vehicles.
