Notes:
10) Use high quality, tight tolorance current sensing resistor. Connect resistor as close as possible to the DIP’s
1) To prevent input signal oscillations minimize wiring length to controller (~2cm). Additional RC filtering (C5 etc.) may be
2) Internal HVIC provides high voltage level shifting allowing direct connection of all six driving signals to the controller.
3) F O 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 t FO , 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 R SHUNT , R SF , C SF must be minimized to avoid improper operation of the SC function.
7) R SF , C SF 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.
