Description
Boot strap supply diode – Ultra fast recovery
Boot strap supply reservoir – Electrolytic, long life, low Impedance, 105°C (Note 5)
Local decoupling/High frequency noise filters – Multilayer ceramic (Note 8)
Control power supply filter – Electrolytic, long life, low Impedance, 105°C
Fault lock-out timing capacitor – Multilayer ceramic (Note 4)
Input signal noise filter – Multilayer ceramic (Note 1)
Main DC bus filter capacitor – Electrolytic, long life, high ripple current, 105°C
Surge voltage suppression capacitor – Polyester/Polypropylene film (Note 9)
Short circuit detection filter capacitor – Multilayer Ceramic (Note 6, Note 7)
Short circuit detection filter resistor (Note 6, Note 7)
Current sensing resistor – Non-inductive, temperature stable, tight tolerance (Note 10)
Boot strap supply inrush limiting resistor (Note 5)
Control input pull-up resistor (Note 1, Note 2)
Fault output signal pull-up resistor (Note 3)
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.

sets the fault output duration and lock-out time. C4 ≈ 12.2E-6
high with 5.1k ohm resistor
x tFO, 22nF gives ~1.8ms
(R3).
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 1.5us-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.
