Product Description
Product Overview
The FNB51060T1 is a Motion SPM 55 module designed for AC Induction, BLDC, and PMSM motors. It offers a fully-featured, high-performance inverter output stage with integrated gate drive and protection features, including under-voltage lockouts, inter-lock function, over-current shutdown, thermal monitoring, and fault reporting. The module utilizes a high-speed HVIC for gate driving, translating logic-level inputs to high-voltage drive signals for robust, short-circuit-rated IGBTs. Separate negative IGBT terminals are provided for flexible control algorithm support.
