1. Electrolytic bus capacitors should be mounted as close to the module bus terminals as possible to reduce ringing and

EMI problems. Additional high frequency ceramic capacitor mounted close to the module pins will further improve perfor-

mance.

2. In order to provide good decoupling between VCC-VSS and VB1,2,3-VS1,2,3 terminals, the capacitors shown connected be-

tween these terminals should be located very close to the module pins. Additional high frequency capacitors, typically

0.1µF, are strongly recommended.

3. Value of the boot-strap capacitors depends upon the switching frequency. Their selection should be made based on

IR design tip DN 98-2a, application note AN-1044 or Figure 9. Bootstrap capacitor value must be selected to limit the

power dissipation of the internal resistor in series with the VCC. (see maximum ratings Table on page 3).

4. Current sense signal can be obtained from pin 22 and pin 23. Care should be taken to avoid having inverter current

flowing through pin 22 to mantain required current measurement accuracy.

5. After approx. 8ms the FAULT is reset. (see Dynamic Characteristics Table on page 5).

6. PWM generator must be disabled within Fault duration to garantee shutdown of the system, overcurrent condition

must be cleared before resuming operation.

7. Fault/Enable pin must be pulled-up to +5V.
