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 performance.
2. In order to provide good decoupling between VCC-VSS and VB1,2,3-VS1,2,3 terminals, the capacitors
shown connected between 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. After approx. 8ms the FAULT is reset. (see Dynamic Characteristics Table on page 5).
5. PWM generator must be disabled within Fault duration to guarantee shutdown of the system, overcurrent
condition must be cleared before resuming operation.
6. Fault/T
