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

Smart Power Module
Features
General Description
• UL Certified No.E209204(SPM27-JA package)
It is an advanced motion-smart power module (Motion-SPMTM)
that Fairchild has newly developed and designed to provide
very compact and high performance ac motor drives mainly targeting low-power inverter-driven application like air conditioner
and washing machine. It combines optimized circuit protection
and drive matched to low-loss IGBTs. System reliability is further enhanced by the integrated under-voltage lock-out and
short-circuit protection. The high speed built-in HVIC provides
opto-coupler-less single-supply IGBT gate driving capability that
further reduce the overall size of the inverter system design.
Each phase current of inverter can be monitored separately due
to the divided negative dc terminals.
• 600V-3A 3-phase IGBT inverter bridge including control ICs
for gate driving and protection
• Easy PCB layout due to built in bootstrap diode
• Divided negative dc-link terminals for inverter current sensing
applications
• Single-grounded power supply due to built-in HVIC
• Isolation rating of 2500Vrms/min.
Applications
• AC 100V ~ 253V three-phase inverter drive for small power
ac motor drives
• Home appliances applications like air conditioner and washing machine

Note:
1) To avoid malfunction, the wiring of each input should be as short as possible. (less than 2-3cm)
2) By virtue of integrating an application specific type HVIC inside the SPM, direct coupling to CPU terminals without any opto-coupler or transformer isolation is possible.
3) VFO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 4.7kΩ resistance. Please refer to Figure 11.
4) CSP15 of around 7 times larger than bootstrap capacitor CBS is recommended.
5) VFO output pulse width should be determined by connecting an external capacitor(CFOD) between CFOD(pin7) and COM(pin2). (Example : if CFOD = 33 nF, then tFO = 1.8ms
(typ.)) Please refer to the note 5 for calculation method.
6) Input signal is High-Active type. There is a 5kΩ resistor inside the IC to pull down each input signal line to GND. RC coupling circuits should be adopted for the prevention of
input signal oscillation. RSCPS time constant should be selected in the range 50~150ns. CPS should not be less than 1nF.(Recommended RS=100Ω , CPS=1nF)
7) To prevent errors of the protection function, the wiring around RF and CSC should be as short as possible.
8) In the short-circuit protection circuit, please select the RFCSC time constant in the range 1.5~2μs.
9) Each capacitor should be mounted as close to the pins of the SPM 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 frequency non-inductive
capacitor of around 0.1~0.22μF between the P&GND pins is recommended.
11) Relays are used at almost every systems of electrical equipments of home appliances. In these cases, there should be sufficient distance between the CPU and the relays.
12) CSPC15 should be over 1μF and mounted as close to the pins of the SPM as possible.
