Typical Application Connection IRAMY20UP60B
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 per-
formance.
2. In order to provide good decoupling between V

and V

terminals, the capacitors shown connected
between these terminals should be located very close to the module pins. Additional high frequency capacitors, typi-
cally 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 V
CC
. (see maximum ratings Table on page 3).
4. Current sense signal can be obtained from pin 20 and pin 23.
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/Temp Monitor pin must be pulled-up to +5V.
