1. Electrolytic bus capacitors should be mounted as close as possible to the module bus terminals to reduce ringing and
EMI problems. Additional high frequency ceramic capacitors mounted close to the module pins will improve perfor-
mance.

terminals, the capacitors connected between these
terminals should be located very close to the module pins. Additional high frequency capacitors, typically 0.1∝F, 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.
4. Current sense signal can be obtained from pin 22 and pin 23
5. After approx. 9 ms the FAULT is reset
6. PWM generator must be disabled within Fault duration to guarantee shutdown of the system, and the overcurrent
condition must be cleared before resuming operation
