FSAM10SH60

FSAM10SH60 - Preliminary October 2001 FSAM10SH60 Smart Power Module (SPM) General Description FSAM10SH60 is an advanced smart power module (SPM) that Fairchild has newly developed and designed to provide very compact and low cost, yet high performance ac motor drives mainly targeting high speed low-power inverterdriven application like washing machines. It combines optimized circuit protection and drive matched to low-loss IGBTs. Highly effective short-circuit current detection/ protection is realized through the use of advanced current sensing IGBT chips that allow continuous monitoring of the IGBTs current. System reliability is further enhanced by the built-in over-temperature and integrated under-voltage lock-out 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 singlesupply drive topology enabling the FSAM10SH60 to be driven by only one drive supply voltage without negative bias. Inverter current sensing application can be achieved due to the devided nagative dc terminals.

RPCPL/RPCPH coupling at each SPM input is recommended in order to prevent input signals’ oscillation and it should be as close as possible to each SPM input pin. 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 Fig. 13. 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(pin8-) and COM(L)(pin2). (Example : if CFOD = 5.6 nF, then tFO = 300 µs (typ.)) Please refer to the note 5 for calculation method. 6. Each input signal line should be pulled up to the 5V power supply with approximately 4.7kΩ resistance (other RC coupling circuits at each input may be needed depending on the PWM control scheme used and on the wiring impedance of the system’s printed circuit board). Approximately a 0.22~2nF by-pass capacitor should be used across each power supply connection terminals. 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 µs. RF should be at least 30 times larger than RSC. (Recommended Example: RSC = 56 Ω, RF = 3.9kΩ, CSC = 1nF and RSU = RSV = RSW = 0Ω) 9. For the use of shunt resistors ( RSU, RSV, RSW ), please see Fig. 6 in order to select the proper RSC. 10.Each capacitor should be mounted as close to the pins of the SPM as possible. 11.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 noninductive capacitor of around 0.1~0.22 uF between the P&N pins is recommended. 12.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. It is recommended that the distance be 5cm at least Fig. 13.
