NAME
FUNCTION
Fault Delay Input. Determines the delay of
the FAULT and FAULT outputs. A capacitor
attached to FLTDLY ensures proper startup
(see the Typical Operating Characteristics ) .

FLTDLY
FLTDLY = GND: holds FAULT low and
FAULT high. When FLTDLY = GND, EN =
high, EN = low, and V CC is within the
operational range, the safety circuitry is
inactive.
Low-Voltage Operation. Connect to GND for
