FSB50550A

Power Driver Modules Overview

The FSB50550A is a Smart Power Module (SPM) from the Motion SPM 5 Series, integrating a three-phase inverter and gate driver for brushless DC (BLDC), permanent magnet synchronous motor (PMSM), and AC induction motor control. It features a 500V collector-emitter voltage rating with a maximum IGBT collector current of 2A. The module operates at a typical switching frequency of 15kHz and provides 1500Vrms isolation. Designed for through-hole installation in a 23-pin PDIP package, it supports a supply voltage range of 13.5V to 16.5V and functions within an ambient temperature range of -40°C to +150°C.

Power Driver Modules Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment prior to assembly. Ensure thermal management solutions meet the specified operating temperature limits. Validate that the application voltage does not exceed the 500V rating. Check for obsolescence status as some variants may be discontinued.

Power Driver Modules Selection Notes

Select this module when designing motor drives requiring integrated protection and drive capabilities. Ensure the load current remains within the 2A limit. Verify compatibility with the required motor type. Consider the 23-pin DIP footprint for PCB layout constraints. Confirm isolation requirements are met by the 1500Vrms specification.

Power Driver Modules Part Context

This component belongs to the Motion SPM 5 Series, which consolidates power semiconductors and drivers into a single unit. Originally developed by Fairchild Semiconductor, the product line was transferred to onsemi following corporate restructuring. The series aims to reduce design complexity and board space for industrial motor control applications.
