General Description
The FNA22512A is a Motion SPM® 2 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 IGBTs to
minimize EMI and losses, while also providing multiple
on-module protection features: under-voltage lockouts,
over-current shutdown, temperature sensing, and fault
reporting. The built-in, high-speed HVIC requires only a
single supply voltage and translates the incoming logic-
level gate inputs to high-voltage, high-current drive
signals to properly drive the module's internal IGBTs.
Separate negative IGBT terminals are available for each
phase to support the widest variety of control algorithms.

c1 : Normal operation: IGBT ON and carrying current.
c2 : Short-circuit current detection (SC trigger).
c3 : All low-side IGBTs gate are hard interrupted.
c4 : All low-side IGBTs turn OFF.
c5 : Fault output operation starts with a fixed pulse width according to the condition of the external capacitor CFOD.
c6 : Input HIGH: IGBT ON state, but during the active period of fault output, the IGBT doesn’t turn ON.
c7 : Fault output operation finishes, but IGBT doesn’t turn on until triggering the next signal from LOW to HIGH.
c8 : Normal operation: IGBT ON and carrying current.

Note:
14. RC coupling at each input might change depending on the PWM control scheme used in the application and the wiring impedance of the application’s printed circuit board.
The input signal section of the Motion SPM 2 product integrates 5 kW (typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay attention to the
signal voltage drop at input terminal.
