The internal fast comparator input may be filtered by placing a small capacitor from FLTR to A. This is useful in situations where the ambient noise or transients might falsely trigger a MOSFET turnoff. While C(FLTR) suppresses small transients, large voltage reversals have a relatively small additional turn-off delay.
FLTR is clamped to C and should only be used with a capacitor as shown in Figure 6. Connections to FLTR should be short and direct to minimize parasitic capacitive loading and crosstalk. The filter pin may not be shorted to any other voltage.
