Product overview
Description
The STSPIN32G0 is a family of highly integrated system-in-package providing solution suitable for driving three-phase brushless motors using different driving modes extremely reducing the BOM and area.
It is composed by four part numbers, for full flexibility in balancing the resources among op-amp for current sensing, GPIOs and specifically dedicated features like a precise reference for the ADC.
It embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 600 mA (sink and source). The high and low-side switches of the 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, for example, the current sensing across the shunt resistors.
A comparator is integrated to perform the overcurrent protection.
The integrated MCU (STM32G031x8) allows performing field oriented control, the 6-step sensorless, and other advanced driving algorithms 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 device also features overtemperature and undervoltage lockout protections and can be put into standby mode to reduce the power consumption. The device provides 23 general-purpose I/O ports (GPIO) , one 12-bit analog-to-digital converter with up to 11 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 embedded bootloader allows flash and option byte management through UART and I2C interfaces.
