Product Introduction

Overview

The FSB50550BB is an advanced Motion SPM 5 module developed by onsemi. This module provides a fully-featured, high-performance inverter output stage designed for driving AC Induction, BLDC (Brushless DC), and PMSM (Permanent Magnet Synchronous) motors. It integrates optimized gate drive of the built-in MOSFETs using FRFET® technology to minimize EMI and losses. The module also includes multiple on-module protection features such as under-voltage lockouts and thermal monitoring.
