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
CC
and the second is if the ITRIP pin recognizes a fault. Once the fault condition occurs, the FAULT pin is
internally pulled to V
SS
and the fault clear timer is activated. The fault output stays in the low state until the fault
condition has been removed and the fault clear timer expires; once the fault clear timer expires, the voltage on the
FAULT pin will return to V
CC
.
The length of the fault clear time period (t
FLTCLR
) is determined by exponential charging characteristics of the
capacitor where the time constant is set by R
RCIN
and C
RCIN
. In Figure 12 where we see that a fault condition has
occurred (UVLO or ITRIP), RCIN and FAULT are pulled to V
SS
, and once the fault has been removed, the fault clear
timer begins. Figure 13 shows that R
RCIN
is connected between the V
CC
and the RCIN pin, while C
RCIN
is placed
between the RCIN and V
SS
pins.
