概述:

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.



主要性能:

UL Certified No.E209204 (SPM27-EC package)
Very low thermal resistance due to using DBC
Easy PCB layout due to built in bootstrap diode
600V-30A 3-phase IGBT inverter bridge including control ICs for gate driving and protection
Divided negative dc-link terminals for inverter current sensing applications
Single-grounded power supply due to built-in HVIC
Isolation rating of 2500Vrms/min.
Key benefits of the Motion-SPM power modules include:
Space and cost savings
Motion-SPM modules in 44mm X 26.8mm Mini-DIP packaging replace 22 discrete components.
Built-in HVIC provides a single-grounded power supply for an optocoupler-less interface
System efficiency
Built-in NPT IGBTs provide optimal tradeoffs between conduction losses and switching losses (FSBB15CH60B (600V/15A): VCE(SAT), typ = 1.6V, E OFF, typ = 28µJ/A)
Short dead time (FSBB15CH60B: tdead = 1.5µs); and
System reliability
Integration of 19 fully tested components
High guaranteed junction temperature (TJ =150°C) and isolation voltage of 2500V
Long short-circuit withstand time
Under-voltage (UV), thermal shutdown (TSD), and short-circuit (SC) protection
These highly integrated devices are packaged in full molded or Direct Bonded Copper (DBC) based Mini-DIP packages. This innovative DBC based Mini-DIP package provides extremely low thermal resistance (FSBB30CH60B (600V/30A): R th(j-c), IGBT = 1.17°C/W).
These Motion-SPM products utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchilds products are designed to meet the requirements of the European Unions Directive on the restriction of the use of certain substances (RoHS).

应用:
AC 100V ~ 253V three-phase inverter drive for small power ac motor rives
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 Figure11.
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.
