Fairchild公司的FNA41560/FNA41560B2是Motion SPM® 45模塊,內置了600V/15A三相IGBT以優化柵極驅動和最小化EMI和損耗,具有多種保護如欠壓鎖住,過流關斷,熱監視和故障報告.器件滿足要UL標準No. E209204 (UL1557),開關頻率5kHz,主要用在家用電器和工業控制的馬達驅動.本文介紹了FNA41560/FNA41560B2主要特性,框圖, 典型應用電路以及FEBSPM3SPM45_M01MTCA Motion SPM3/45H評估板主要特性,電路圖,材料清單和PCB元件布局圖與PCB走線圖.
FNA41560/FNA41560B2 is a Motion SPM® 45 module providing a fully-featured, high performance inverter output stage for AC Induction, BLDC, and PMSM motors.
These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, thermal monitoring, and fault reporting. The built-in, highspeed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s robust short-circuit-rated IGBTs.
Separate negative IGBT terminals are available for each phase to support the widest variety of control algorithms.

FEBSPM3SPM45_M01MTCA Motion SPM3/45H評估板
This motion Smart Power Module (SPM®) evaluation board is designed to evaluate Fairchild Semiconductor’s SPM3V2_V4 and SPM45H SPM families of parts. The motion SPM is installed as the motor power module on the evaluation board to drive a three-phase AC Induction Motor (ACIM), Brushless DC (BLDC) motor, Brushless AC (BLAC) motor, or Permanent-Magnet Synchronous Motor (PMSM). A Switched-Mode Power Supply (SMPS) is integrated into the design, along with the necessary bulk capacitors and microcontroller (MCU) interface circuitry. This allows evaluation of Fairchild’s motion SPM products with a minimum investment of time, expense, and peripheral equipment. As this board is designed for a wide variety of motor types, not all included circuitry is required for all types of motors. Some motor types may require some additional circuitry be added, depending on the control algorithms being implemented.
By default, the FNB41560 (600 V/15 A SPM45H) is installed as the motor power module, as shown in Figure 9. It is possible to replace the provided SPM45H module with a part from the SPM3_V2 family (i.e. FSBB30CH60, 600 V/30 A) per Figure 10 or the SPM3_V4 family (i.e. FSBB30CH60C, 600 V/30 A) per Figure 11. Depending on the power level of the device, some additional discrete component value changes may be required. The most common reason to consider a SPM3V2_V4 device over the SPM45H family is to increase motor power level.
The evaluation board is designed to connect to either AC or DC power sources feeding current to the motor. There are three example test configurations in Section 3. The three-phase motor output terminals (U, V, W) from the SPM should be connected to the motor windings. Three bootstrap power supply circuits are designed into the evaluation board, one per phase. A bootstrap capacitor, charge resistor for charging the capacitor, and the blocking diode for high-voltage isolation make up each bootstrap supply. With SPM45H and SPM3_V4 modules, R50-55 and D5-7 are not required. These extra bootstrap positions are provided for compatibility with SPM3_V2 modules.
The microcontroller (MCU) or motion-controller development board connects to this SPM board via the provided connector. Six low-pass filters are used between the signal input connector and the gate input signal pins of the FNB41560. Short-circuit current protection is provided by a single shunt resistor, op amp, and low-pass filter. Additional circuitry is included to monitor bus voltage, inverter phase current, and module temperature. This evaluation board is designed to support a wide array of test conditions and requirements.
