3. Key Technical Points & Notifications:

️· High-Side/Low-Side Drives: Separate pins for biasing and controlling the high-side and low-side IGBTs are provided.
️· Signal Inputs: The signal inputs (IN(UL), IN(VL), IN(WL)) are active-high and use a Schmitt trigger for noise immunity.
️· Fault Output (VFO): This is an open-drain output and requires an external pull-up resistor (around 4.7kΩ) to a 5V supply.
️· Thermistor Temperature Detection: RTH and VTH pins are used for thermistor based temperature monitoring.
️· Bootstrap Circuitry: Bootstrap diodes and capacitors are used to generate the higher gate drive voltage for the high-side IGBTs.
️· Negative DC-link Pins: NU, NV, and NW are the negative DC link pins.

4. Electrical Specifications (Highlights):

️· VPN (Supply Voltage): 900V
️· VPN(Surge): 1000V
️· VCES (Collector-Emitter Voltage): 1200V
️· Current Ratings: Depends on the specific model (FNA21012A, FNA22512A, FNA23512A) – ranging from 10A to 35A continuous and higher peak currents.
