Smart Power Module (SPM®)
Features
•500V R
DS(on)=1.4Ω(max) 3-phase FRFET inverter including
high voltage integrated circuit (HVIC)
3 divided negative dc-link terminals for inver ter current sens-
ing 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.
General Description
FSB50550U 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 M OSFET (FRFET),
and 3 half-bridge HVICs for FRFET gate driving. FSB50550U
provides low electromagnetic interference (EMI) char acteristics
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. F SB50550U is the most solution
for the compact inverter providing the energy efficiency,
compactness, and low electromagnetic interference.

Note:
1. For the measurement point of case temperatur e 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.

Recommended Operating Conditions
Note:
(1) It is recommended the bootstrap diode D1 to have soft and fast recovery characteristics with 600-V rating
(2) Parameters for bootsrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of para meters is shown above.
(3) RC coupling (R5 and C5) at each input (indicat ed as dotted lines) may be used to prevent improper input sig nal due to surge nois e. 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. Recommended CPU Interface and Bootstrap Circuit with Parameters
Note:
Attach the thermocouple on top of the heatsink-side of SPM® (between SPM® and heatsink if applied) to get the correct temperature measurement.
