Continuous restart mode is enabled by connecting the
FAULT output to VMIN through a 0.1 F capacitor, as
shown in Figure 3-1. When so connected, the TC647
automatically attempts to restart the fan whenever a
fault condition occurs. When the FAULT output is
driven low, the VMIN input is momentarily pulled below
VSHDN, initiating a reset and clearing the fault
condition. Normal fan start-up is then attempted as pre-
viously described. The FAULT output may be
connected to external logic (or the interrupt input of a
microcontroller) to shut the TC647 down if multiple fault
pulses are detected at approximately one second
intervals.
