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, the 6-stepsensorless and other advanced driving algorithm including the speed control loop. It has thewrite-protection and read-protection feature for the embedded Flash memory to protectagainst 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 analog-to-digital converter with up to 9 channels performing conversions in a singleshotor scan modes,
