FCAS50SN60
Smart Power Module for SRM Features
* Very low thermal resistance due to using DBC * 600V-50A single-phase asymmetric bridge IGBT converter for SRM drive 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 * Switching frequency of 2.2~8kHz * Isolation rating of 2500Vrms/min.
General Description
FCAS50SN60 is an advanced smart power module for SRM drive that Fairchild has newly developed and designed to provide very compact and high performance SRM motor drives mainly targeting low-power inverter-driven SRM application especially for a vacuum air cleaner. 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 IGBT gate driving capability that further reduce the overall size of the inverter system design. In addition the incorporated HVIC facilitates the use of single-supply drive topology enabling the FCAS50SN60 to be driven by only one drive supply voltage without negative bias. Each phase current of inverter can be monitored separately due to the divided negative dc terminals.
Applications
* AC 200V ~ 242V single-phase SRM drives for home application vacuum cleaner.

Note: 1. RC coupling at each input (parts shown dotted) might change depending on the PWM control scheme used in the application and the wiring impedance of the application's printed circuit board. The input signal section integrates 3.3k(typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay attention to the signal voltage drop at input terminal. 2. The logic input is compatible with standard CMOS or LSTTL outputs.

Input Signal for Short-Circuit Protection
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 Module, 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 4.7k resistance. Please refer to Figure 10. 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 6 for calculation method. 6. Input signal is High-Active type. There is a 3.3k resistor inside the IC to pull down each input signal line to GND. When employing RC coupling circuits, set up such RC couple that input signal agree with turn-off/turn-on threshold voltage. 7. To prevent errors of the protection function, the wiring around RSC, 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 3~4 s. 9. Each capacitor should be mounted as close to the pins as possible. 10. To prevent surge destruction, the wiring between the smoothing capacitor and the P&N pins should be as short as possible. The use of a high frequency non-inductive capacitor of around 0.1~0.22 F between P and N 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 1uF and mounted as close to the pins of the module as possible. 13. NB1(pin23) and NB2(pin21) should be shorted externally.
