STSPIN32F0 Introduction
The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes.
The STSPIN32F0 embedded a STM32F031C6 plus gate driver able to drive power MOSFETs or IGBTs.
For more info regarding Electrical Motors see here.
It embeds a triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability of 600 mA (sink and source). The high and low side switches of same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function.
An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and external components.
An internal LDO linear regulator provides the supply voltage for gate drivers.
The integrated operational amplifiers are available for the signal conditioning of the analog Hall-effect sensors and the shunt resistor signal.
A comparator with a programmable threshold is integrated to perform the overcurrent protection.
The integrated MCU (STM32F031x6x7) allows performing field-oriented control (FOC), the 6-step sensorless and other advanced driving algorithm including the speed control loop. It has the write-protection and read-protection feature for the embedded Flash memory to protect against unwanted writing and/or reading.
The STSPIN32F0 device also features overtemperature and undervoltage lockout protections and can be put in the standby mode to reduce the power consumption. The device provides 16 general-purpose I/O ports (GPIO) with the 5 V tolerant capability, one 12-bit ADC with up to 9 channels performing conversions in a single-shot or scan modes, 5 synchronizable general-purpose timers and supports an easy to use debugging serial interface (SWD).
The examples are in the STSW-SPIN3201 and are ready to use for the BULL RUNNING BR2804-1700KV motor.
