Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

General Description
FNB41560 / FNB41560B2 i s an advanced 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 fea-
tures including under-voltage lockouts, over-current
shutdown, thermal monitoring, and fault reporting. The
built-in, high-speed 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-cir-
cuit-rated IGBTs. Separate negative IGBT te rminals are
available for each phase to support the widest variety of
control algorithms.

Figure 15. Typical Application Circuit
3rd Notes:
1) To avoid malfunction, the wiring of each input should be as short as possible (less than 2 - 3 cm).
2) By virtue of integrat ing an application-specific type of HVIC insi de the M oti o n SPM® 45 pr od uct , dire ct coup l in g to MCU ter m i na ls w ithout any optocoupler or transformer isol a-
tion is possible.
3) VFO output is open-drain type . This signal line should be pulled up to the positive side of the MCU or control power supply with a resistor that makes IFO up to 1 mA (please
refer to Figure 14).
4) CSP15 of around seven times larger than bootstrap capacitor CBS is recommended.
5) Input signal is active-HIGH type. There is a 5 k resistor inside the IC to pull down each input signal line to GND. RC coupling circuits is recommanded for the prevention of
input signal oscillation. RSCPS time constant should be selected in the range 50 ~ 150 ns (recommended RS = 100 Ω, CPS = 1 nF).
6) To prevent errors of the protection function, the wiring around RF and CSC should be as short as possible.
7) In the short-circuit protection circuit, please select the RFCSC time constant in the range 1.5 ~ 2 s.
8) The connection between con trol GND line and power GND line which includes the NU, NV, NW must be connected to only one point. Please do not connect the control GND
to the power GND by the broad pattern. Also, the wiring distance between control GND and power GND should be as short as possible.
9) Each capacitor should be mounted as close to the pins of the Motion SPM 45 product as possible.
10) To prevent surge destruction, the wiring between the smoothing capacitor and the P & GND pins should be as short as possible. The use of a high-f requen cy no n-ind ucti ve
capacitor of around 0.1 ~ 0.22 F between the P and GND pins is recommended.
11) Relays are used in almost every systems of electrical equipment in home appliances. In these cases, there should be sufficient distance between the MCU and the relays.
12) The zener diode or transient voltage suppressor should be adopted for the protection of ICs from the surge destruction between each pair of control supply terminals
(recommanded zener diode is 22 V / 1 W, which has the lower zener impedance characteristic than about 15 Ω).
13) Please choose the electrolytic capacitor with good temperature characteristic in CBS. Also, choose 0.1 ~ 0.2 F R-category ceramic capacitors with good temperature and
frequency characteristics in CBSC.
14) For the detailed information, please refer to the AN-9070, AN-9071, AN-9072, RD-344, and RD-345.
