Fault Reporting and Programmable Fault Clear Timer
The IRS2336xD family provides an integrated fault reporting output and an adjustable fault clear timer. There are two
situations that would cause the HVIC to report a fault via the FAULT pin. The first is an undervoltage condition of V
and the second is if the ITRIP pin recognizes a fault. Once the fault condition occurs, the FAULT pin is internally
pulled to V
been removed and the fault clear timer expires; once the fault clear timer expires, the voltage on the FAULT pin will
return to V
The length of the fault clear time period (t
where the time constant is set by R
(UVLO or ITRIP), RCIN and FAULT are pulled to V
begins. Figure 13 shows that R

The design guidelines for this network are shown in Table 3.
The length of the fault clear time period can be determined by using the formula below.
