FLT1

Over-temperature event diagnostic pin

IPD

Initial current duration / level selector.

Connect to GND by a capacitor to set duration of

IPKH (see Section 7.3 and Table 9 / Table 10).

Connect to IN pin by a 220 kΩ resistor to disable

initial IPKH threshold (the over-current limit is only

IPKL).

Connect to GND by a 10 kΩ resistor to disable

IPKL (the over-current threshold is only IPKH).

Note:

Leaving IPD floating is equivalent to a

1 µs duration for IPKH.
