FSB50450BL Description

Short technical summary and product information.

The FSB50450BL is a Motion SPM 5 Series power driver module from onsemi, integrating six FRFET MOSFETs in a 3-phase inverter configuration with gate drivers and protection. It features a maximum drain-source voltage of 500V and continuous drain current of 2.2A at TC=25°C (1.4A at TC=80°C). Peak current is 5A, and RMS current at 80°C is 1A. The module provides 1500Vrms isolation and is optimized for switching frequencies above 10 kHz.

 

The logic interface is active-HIGH with Schmitt-trigger inputs compatible with 3.3V and 5V logic. Built-in bootstrap diodes simplify PCB layout, and separate open-source pins enable three-phase current sensing. Protection features include under-voltage lockout and thermal monitoring.

 

The module is housed in a through-hole 23-PowerDIP package (0.551", 14.00mm) with case code SPM5E-023. It is UL certified (E209204) and the datasheet indicates Pb-Free and RoHS compliance. Typical applications include small power AC motor drives for BLDC, PMSM, and AC induction motors.
