FSAM50SM60A SPMTM (Smart Power Module) General Description Features FSAM50SM60A 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 medium speed low-power inverter-driven application like air conditioners. 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 FSAM50SM60A 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. • UL Certified No. E209204 • 600V-50A 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 • Typical switching frequency of 5kHz • Built-in thermistor for over-temperature monitoring • Isolation rating of 2500Vrms/min. • Very low leakage current due to using DBC (Direct Bonded Copper) substrate • Adjustable current protection level by varying series resistor value with sense-IGBTs Applications • AC 100V ~ 253V three-phase inverter drive for small power ac motor drives • Home appliances applications like air conditioners drive system External View Top View Bottom View 60mm 31mm Fig. 1. ©2006 Fairchild Semiconductor Corporation April 3, 2006 FSAM50SM60A April 3, 2006 FSAM50SM60A Integrated Power Functions • 600V-50A IGBT inverter for three-phase DC/AC power conversion (Please refer to Fig. 3) Integrated Drive, Protection and System Control Functions • For inverter high-side IGBTs: Gate drive circuit, High voltage isolated high-speed level shifting Control circuit under-voltage (UV) protection Note) Available bootstrap circuit example is given in Figs. 13 and 14. • For inverter low-side IGBTs: Gate drive circuit, Short circuit protection (SC) Control supply circuit under-voltage (UV) protection • Temperature Monitoring: System over-temperature monitoring using built-in thermistor Note) Available temperature monitoring circuit is given in Fig. 14. • Fault signaling: Corresponding to a SC fault (Low-side IGBTs) or a UV fault (Low-side control supply circuit) • Input interface: 5V CMOS/LSTTL compatible, Schmitt trigger input Pin Configuration Top View (1)VCC(L) (2)COM(L) (3)IN(UL) (4)IN(VL) (5)IN(WL) (6)COM(L) (24)VTH (25)RTH (26)NU (27)NV (7)VFO (8)CFOD (9)CSC (28)NW (10)RSC (11)IN(UH) (29)U (12)VCC(UH) (13)VB(U) Case Temperature(TC) Detecting Point (30)V (14)VS(U) (15)INV(H) (16)COM(H) (17)VCC(VH) (31)W (18)VB(V) DBC Substrate (19)VS(V) (20)IN(WH) (32)P (21)VCC(WH) (22)VB(W) (23)VS(W) Fig. 2. ©2006 Fairchild Semiconductor Corporation April 3, 2006 FSAM50SM60A Pin Descriptions Pin Number 1 Pin Name VCC(L) Pin Description Low-side Common Bias Voltage for IC and IGBTs Driving 2 COM(L) 3 IN(UL) Signal Input Terminal for Low-side U Phase 4 IN(VL) Signal Input Terminal for Low-side V Phase 5 IN(WL) Signal Input Terminal for Low-side W Phase 6 COM(L) Low-side Common Supply Ground 7 VFO 8 CFOD Capacitor for Fault Output Duration Time Selection 9 CSC Capacitor (Low-pass Filter) for Short-Circuit current Detection Input 10 RSC 11 IN(UH) 12 VCC(UH) 13 VB(U) High-side Bias Voltage for U Phase IGBT Driving 14 VS(U) High-side Bias Voltage Ground for U Phase IGBT Driving 15 IN(VH) Signal Input for High-side V Phase 16 COM(H) High-side Common Supply Ground 17 VCC(VH) High-side Bias Voltage for V Phase IC 18 VB(V) High-side Bias Voltage for V Phase IGBT Driving 19 VS(V) High-side Bias Voltage Ground for V Phase IGBT Driving 20 IN(WH) 21 VCC(WH) 22 VB(W) High-side Bias Voltage for W Phase IGBT Driving 23 VS(W) High-side Bias Voltage Ground for W Phase IGBT Driving 24 VTH Thermistor Bias Voltage 25 RTH Series Resistor for the Use of Thermistor (Temperature Detection) 26 NU Negative DC–Link Input Terminal for U Phase 27 NV Negative DC–Link Input Terminal for V Phase 28 NW 29 U Low-side Common Supply Ground Fault Output Resistor for Short-circuit Current Detection Signal Input for High-side U Phase High-side Bias Voltage for U Phase IC Signal Input for High-side W Phase High-side Bias Voltage for W Phase IC Negative DC–Link Input Terminal for W Phase Output for U Phase 30 V Output for V Phase 31 W Output for W Phase 32 P Positive DC–Link Input ©2006 Fairchild Semiconductor Corporation April 3, 2006 FSAM50SM60A Internal Equivalent Circuit and Input/Output Pins Bottom View (22) VB(W) (21) VCC(WH) (20) IN(WH) (23) VS(W) (18) VB(V) (17) VCC(VH) (16) COM(H) (15) IN(VH) (19) VS(V) (13) VB(U) (12) VCC(UH) (11) IN(UH) (14) VS(U) P (32) VB VCC COM IN OUT W (31) VS VB VCC COM IN OUT VS V (30) VB VCC COM IN OUT U (29) VS (10) RSC (9) CSC (8) CFOD (7) VFO (6) COM(L) (5) IN(WL) (4) IN(VL) (3) IN(UL) (2) COM(L) (1) VCC(L) C(SC) OUT(WL) C(FOD) NW (28) VFO IN(WL) OUT(VL) IN(VL) NV (27) IN(UL) COM(L) OUT(UL) VCC NU (26) RTH (25) THERMISTOR VTH (24) Note 1.

Short-circuit current protection is functioning only at the low-sides. It would be recommended that the value of the external sensing resistor (RSC) should be selected around 40 Ω in order to make the SC trip-level of about 75A at the shunt resistors (RSU,RSV,RSW) of 0Ω . For the detailed information about the relationship between the external sensing resistor (RSC) and the shunt resistors (RSU,RSV,RSW), please see Fig. 6. 6. The fault-out pulse width tFOD depends on the capacitance value of CFOD according to the following approximate equation : CFOD = 18.3 x 10-6 x tFOD[F] 7. TTH is the temperature of thermistor itself.

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. 12. 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 = 33 nF, then tFO = 1.8 ms (typ.)) Please refer to the note 6 for calculation method. 6) Each input signal line should be pulled up to the 5V power supply with approximately 4.7kΩ (at high side input) or 2kΩ (at low side input) 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. 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&N pins should be as short as possible. The use of a high frequency noninductive capacitor of around 0.1~0.22 µF between the P&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. It is recommended that the distance be 5cm at least. Fig. 14.
