General Description
The FSB50325A/AT/AS is an advanced Motion SPM® 5
module providing a fully-featured, high-performance
inverter output stage for AC Induction, BLDC and PMSM
motors. These modules integrate optimized gate drive of
the built-in MOSFETs(FRFET® technology) to minimize
EMI and losses, while also providing multiple on-module
protection features including under-voltage 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.

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 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 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.
