FSB50325T Smart Power Module (SPM) Features General Description • 250V 3.0A 3-phase FRFET inverter including high voltage integrated circuit (HVIC) FSB50325T is a tiny smart power module (SPM) based on FRFET technology as a compact inverter solution for small power motor drive applications such as fan motors and water suppliers. It is composed of 6 fast-recovery MOSFET (FRFET), and 3 half-bridge HVICs for FRFET gate driving. FSB50325T provides low electromagnetic interference (EMI) characteristics with optimized switching speed. Moreover, since it employs FRFET as a power switch, it has much better ruggedness and larger safe operation area (SOA) than that of an IGBT-based power module or one-chip solution. The package is optimized for the thermal performance and compactness for the use in the built-in motor application and any other application where the assembly space is concerned. FSB50325T is the most solution for the compact inverter providing the energy efficiency, compactness, and low electromagnetic interference. • 3 divided negative dc-link terminals for inverter current sensing applications • HVIC for gate driving and undervoltage protection • 3/5V CMOS/TTL compatible, active-high interface • Optimized for low electromagnetic interference • Isolation voltage rating of 1500Vrms for 1min. • Extended VB pin for PCB isolation Absolute Maximum Ratings Symbol Parameter Conditions Rating Units 250 V VPN DC Link Input Voltage, Drain-source Voltage of each FRFET ID25 Each FRFET Drain Current, Continuous TC = 25°C 1.5 A ID80 Each FRFET Drain Current, Continuous TC = 80°C 1.0 A IDP Each FRFET Drain Current, Peak TC = 25°C, PW < 100µs 3.0 A PD Maximum Power Dissipation TC = 25°C, Each FRFET 10 W VCC Control Supply Voltage Applied between VCC and COM 20 V VBS High-side Bias Voltage Applied between VB(U)-U, VB(V)-V, VB(W)-W 20 V VIN Input Signal Voltage Applied between IN and COM -0.3 ~ VCC+0.3 V TJ Operating Junction Temperature -20 ~ 125 °C TSTG Storage Temperature -50 ~ 150 °C RθJC Junction to Case Thermal Resistance Each FRFET under inverter operating condition (Note 1) 10.2 °C/W VISO Isolation Voltage 60Hz, Sinusoidal, 1 minute, Connection pins to heatsink 1500 Vrms ©2005 Fairchild Semiconductor Corporation FSB50325T Rev.

For the measurement point of case temperature TC, please refer to Figure 3 in page 4. 2. BVDSS is the absolute maximum voltage rating between drain and source terminal of each FRFET inside SPM. VPN should be sufficiently less than this value considering the effect of the stray inductance so that VDS should not exceed BVDSS in any case. 3. tON and tOFF include the propagation delay time of the internal drive IC. Listed values are measured at the laboratory test condition, and they can be different according to the field applcations due to the effect of different printed circuit boards and wirings. Please see Figure 4 for the switching time definition with the switching test circuit of Figure 5. 4. The peak current and voltage of each FRFET during the switching operation should be included in the safe operating area (SOA). Please see Figure 5 for the RBSOA test circuit that is same as the switching test circuit. 3 FSB50325T Rev.

For 15 kHz of switching frequency, typical example of parameters is shown above. (3) RC coupling(R5 and C5) at each input (indicated as dotted lines) may be used to prevent improper input signal due to surge noise. Signal input of SPM is compatible with standard CMOS or LSTTL outptus. (4) Bold lines should be short and thick in PCB pattern to have small stray inductance of circuit, which results in the reduction of surge voltage. Bypass capacitors such as C1, C2 and C3 should have good high-frequency characteristics to absorb high-frequency ripple current. Figure 2.
