5. A NTC is generally placed between the SD and GND pins. Parameters RTF(start), RTF(stop), ROTP(off) and ROTP(on) give the resistance the
NTC must exhibit to respectively, enter thermal foldback, stop thermal foldback, trigger the OTP limit and allow the circuit recovery after
an OTP situation.
Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
6. Guaranteed by design.
