General Description
The FSB50250A/AT is an advanced Motion SPM® 5
module providing a fully-featured, high-performance
inverter output stage for AC Induction, BLD C and PMSM
motors. These modules integrate optimized gate drive of
the built-in MOSFET s (FRFET® technology) to minimize
EMI and losses, while also providing multiple on-module
protection features including under-voltag e lockouts and
thermal monitoring. The built-in high-speed
HVIC requires only a single supply voltage and
translates the incoming logic-level gate inputs to the
high-voltage, high-current drive signals required to
properly drive the module's internal MOSFETs.
Separate open-source MOSFET terminals are available
for each phase to support the widest variety of control
algorithms.

2nd Notes:
1. BVDSS is the absolute maxi mum voltage rating between drain and source terminal of each MOSFET inside Motion SPM® 5 product. VPN sho uld be sufficiently less than this
value consideri ng the ef f ect of the str ay inductance so that VPN should not exceed BVDSS in any case.
2. tON and tOFF include the propagation delay of the internal drive IC. Listed values are measured at the laboratory test condition, and they can be different according to the field
applications 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 MOSFET 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 modu l e and can not shut down MOSFETs automatically.
5. Built-in bootstrap diode includes around 15 Ωresistance characteristic. Please refer to Figure 2.

Figure 3. Recommended MCU Interface and Bootstrap Circuit with Parameters
3rd Notes:
1. Parameters for bootstrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of parameters is shown above.
2. RC-coupli ng (R 5 and C5) and C4 at each input of Motion SPM 5 product and MCU (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 cap acitors such as C1, C2
and C3 should have good high-frequency characteristics to absorb high-frequency ripple-current.

3rd Notes:
4. Attach the thermocouple on top of the heat-sink of SPM 5 package (between SPM 5 package and heatsink if applied) to get the corr ect temperature measurement.

Figure 10. Example of Application Circuit
4th Notes:
1. About pin position, refer to Figure 1.
2. RC-coupling (R5 and C5, R4 and C6) and C4 at each input of Motion SPM® 5 product and MCU are use ful to prevent improper input signal c aused by surge-noise.
3. The voltage -drop acros s 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 1 V 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 should be connected close to Motion SPM 5 product, and they should have good characteristics for rejecting high-frequency ripple current.
