OTHER EXTRA COMPONENTS
These components are provided to make IRMD22141SS board as customizable as possible. In many
cases the extra components are not required.
Desat circuit
The IR22141S is able to detect the IGBT desaturation. To reject the noise on the desat pins the
IR22141SS have an internal filter of 1
sec. If this is not enough an RC filter has been placed on board
(see figure 8, R

Figure 8: Desat external filter
The external resistor is in parallel with the internal bias circuit of the desat diode. If added, the external
resistor may cause an higher diode bias current that must be taken into account in bootstrap capacitor
sizing.
External RC filter delays desaturation detection, that causes a delay in turning the IGBT off. Consider
this delay when sizing the soft-shut-down resistors.
