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)

Optional 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)

Optional control input noise filter (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 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.

controller.

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 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 a 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.
