FNA41560

Power Driver Modules Overview

The FNA41560 is a Motion SPM 45 series intelligent power module featuring a three-phase IGBT inverter rated at 600V and 15A. It integrates optimized gate drivers, under-voltage lockout, over-current shutdown, thermal monitoring, and fault reporting. The module utilizes a ceramic substrate for low thermal resistance and includes built-in bootstrap diodes with dedicated Vs pins to simplify PCB layout. Separate open-emitter pins on the low-side IGBTs enable precise three-phase current sensing. Designed for single-grounded power supply operation, it supports logic-level inputs via an internal high-speed HVIC.

Power Driver Modules Feature Summary

• Integrated protection mechanisms including under-voltage lockout, over-current shutdown, and thermal monitoring with fault reporting capabilities.
• Optimized gate drive system that minimizes electromagnetic interference and energy losses while translating logic-level signals to high-voltage drive requirements.
• Simplified printed circuit board design through the inclusion of built-in bootstrap diodes and dedicated voltage sense pins.
• Enhanced control flexibility provided by separate negative terminals for each phase to support diverse motor control algorithms.

Power Driver Modules Applications

• Motion control systems for home appliances such as washing machines and air conditioners
• Industrial motor drives requiring efficient AC induction or BLDC motor management
• Permanent magnet synchronous motor (PMSM) applications

Power Driver Modules Procurement Notes

Verify component status carefully as the FNA41560 is marked Not Recommended for New Designs (NRND). Confirm availability through authorized distributors and check for lead time variations due to production cycles. Ensure replacement strategies are evaluated if long-term supply stability is required for new product development projects.

Power Driver Modules Selection Notes
