Overview
The FNB41560 and FNB41560B2 are advanced Motion SPM® 45 modules produced by onsemi. These modules provide a fully-featured, high-performance inverter output stage designed for AC Induction, BLDC (Brushless DC), and PMSM (Permanent Magnet Synchronous Motor) motors. They integrate optimized gate drive for the built-in IGBTs, minimizing EMI and losses, and offer multiple on-module protection features including under-voltage lockouts, over-current shutdown, thermal monitoring, and fault reporting. The modules require only a single supply voltage and translate incoming logic-level gate inputs to high-voltage, high-current drive signals necessary for driving the robust short-circuit-rated IGBTs.
