STSPIN32F0 overcurrent protection
Dario Cucchi
Introduction
The STSPIN32F0 device is a system-in-package providing an integrated solution suitable
for driving three-phase BLDC motors using different driving modes. One of the integrated
features of this device is overcurrent protection, which protects the application against
damaging when high currents are reached.
The protection is implemented using an integrated comparator with an adjustable threshold.
The overcurrent event can be managed both by the gate driving logic and by the
microcontroller, according to user selection.
This document gives an overview of the OC protection feature and explains how to connect
the STSPIN32F0 pins in order to implement the desired current threshold.
