1) To prevent input signal oscillations minimize wiring length to controller (~2cm). Additional RC filtering (C5 etc.) may be required.
If filtering is added be careful to maintain proper dead time and voltage levels. See application notes for details.
2) Internal HVIC provides high voltage level shifting allowing direct connection of all six driving signals to the controller.
3) FO output is an open collector type. Pull up resistor (R3) should be adjusted to current sink capability of the controller.
4) Use only one VNC Pin (either 9 or 16) and leave the other open.
5) Boot strap supply component values must be adjusted depending on the PWM frequency and technique.
6) Wiring length associated with RSHUNT, RSF, CSF must be minimized to avoid improper operation of the OC function.
7) RSF, CSF set over current protection trip time. Recommend time constant is 1.5µs-2.0µs. See application notes.
8) Local decoupling/high frequency filter capacitors must be connected as close as possible to the modules pins.
9) The length of the DC link wiring between C5, C6, the DIP’s P terminal and the shunt must be minimized to prevent excessive
transient voltages. In particular C6 should be mounted as close to the DIP as possible.
10) Use high quality, tight tolerance current sensing resistor. Connect resistor as close as possible to the DIP’s N terminal. Be careful
to check for proper power rating. See application notes for calculation of resistance value.
