Notes:

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. 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 module.

4) C4 sets the fault output duration and lock-out time. C4 12.2E-6 x tFO, 22nF gives ~1.8ms

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 SC function.

7) RSF, CSF set short-circuit protection trip time. Recommend time constant is 1.5us-2.0us. 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 C6, C7, the DIP’s P terminal and the shunt must be minimized to prevent

excessive transient voltages. In particular C7 should be mounted as close to the DIP as possible.

10) Use high quality, tight tolorance 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.
