FNA41560B2

Power Driver Modules Overview

The FNA41560B2 is a Motion SPM 45 series smart power module from onsemi, designed for AC induction, BLDC, and PMSM motor drives. It integrates a 600V, 15A three-phase IGBT inverter with optimized gate drivers to minimize EMI and switching losses. The module features a ceramic substrate for low thermal resistance and includes built-in protection mechanisms such as under-voltage lockout, over-current shutdown, and thermal monitoring via an NTC thermistor. It operates within a temperature range of -40°C to +150°C and supports single-grounded power supply configurations.

Power Driver Modules Procurement Notes

Verify the component status carefully, as some sources indicate it may be Not Recommended for New Designs (NRND). Confirm the specific ordering suffix matches your requirements, noting that manufacturer system integrations may have altered naming conventions from previous Fairchild designs. Always cross-reference the latest datasheet for electrical ratings and mechanical dimensions before finalizing procurement specifications.

Power Driver Modules Selection Notes

Select this module when designing for 600V/15A three-phase inverter stages requiring integrated protection and low thermal resistance. It is suitable for applications optimized around a 5 kHz switching frequency. Ensure the design accommodates the SPM26-AAC through-hole package and utilizes the dedicated Vs pins for simplified PCB layout. Verify that the control algorithm can leverage the separate emitter pins for accurate current sensing.
