STSPIN32F0B数据手册集成电路（IC）的应用特定微控制器规格书PDF

描述 Description

The STSPIN32F0B is a System-In-Package providing an integrated solution suitable for driving three-phase brushless motors using different driving modes.

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 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 amplifier is available for the signal conditioning, e.g. the current sensing across the shunt resistor.

A comparator with a programmable threshold is integrated to perform the overcurrent protection.

The integrated MCU (STM32F031C6 with extended temperature range, suffix 7 version) allows performing fieldoriented control, the 6-step sensorless and other advanced driving algorithms. It has the write-protection and read-protection feature for the embedded Flash memory to protect against unwanted writing and/or reading. It is possible to download the firmware on-the-field through the serial interface thanks to the embedded bootloader.

The STSPIN32F0B device also features overtemperature and undervoltage lockout protections and can be put in the standby mode to reduce the power consumption. The device provides 20 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 single-shot or scan modes, 5 synchronizable general-purpose timers and supports an easy to use debugging serial interface (SWD).
