Smart Power Module (SPM®)
Features
Applications
• 250V RDS(on) =0.45W(max) 3-phase FRFET inverter including
high voltage integrated circuit (HVIC)
• Three-phase inverter driver for small power ac motor drives
General Description
• 3 divided negative dc-link terminals for inverter current sensing applications
FSB50825AS 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. FSB50825AS
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. FSB50825AS is the best
solution for the compact inverter providing the energy efficiency,
compactness, and low electromagnetic interference.
• HVIC for gate driving and undervoltage protection
• Optimized for low electromagnetic interference
• Isolation voltage rating of 1500Vrms for 1min.
• HVIC temperature sensing
• Embedded bootstrap diode in the package
• Moisture Sensitive Level (MSL) 3
• RoHS compliant

Note:
1. 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.
2. 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 6 for the switching time definition with the switching test circuit of Figure 7.
3. The peak current and voltage of each FRFET during the switching operation should be included in the safe operating area (SOA). Please see Figure 7 for the RBSOA test circuit that is same as the switching test circuit.
4. Vts is only for sensing temperature of module and cannot shutdown MOSFETs automatically.
5. Built in bootstrap diode includes around 15 Ω resistance characteristic. Please refer to Figure 2.

* Example of bootstrap paramters
:
C1 = C2 =1mF ceramic capacitor
Note:
1. Parameters for bootsrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of parameters is shown above.
2. RC coupling(R5 and C 5) and C 4 at each input of SPM® and Micom (indicated as dotted lines) may be used to prevent improper signal due to surge noise.
3. 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-frequencycharacteristics to absorb high-frequency ripple current.

Attach the thermocouple on top of the heatsink-side of SPM® (between SPM® and heatsink if applied) to get the correct temperature measurement.

Note:
1. About pin position, refer to Figure 2.
2. RC coupling(R5 and C5, R4 and C 6) and C 4 at each input of SPM® and Micom are useful to prevent improper input signal caused by surge noise.
3. The voltage drop across R3 affects the low side switching performance and the bootstrap characteristics since it is placed between COM and the source terminal of the low side
MOSFET. For this reason, the voltage drop across R3 should be less than 1V in the steady-state.
4. Ground wires and output terminals, should be thick and short in order to avoid surge voltage and malfunction of HVIC.
5. All the filter capacitors shoud be connected close to SPM®, and they should have good characteristics for rejecting high-frequency ripple current.

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from fairchild directly or from Authorized Fairchild
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
