3. Glossary of Terms
MilliTesla (mT), Gauss: Units of magnetic flux density; 1 milliTesla = 10 Gauss.
Two-Coil Fan: a fan with two coil windings, current alternates from 1 coil to the other depending on the
polarity of the magnetic field.
Two-wire Fan: A fan that has only two connections for the power supply plus and minus.
Locked rotor: The condition of a fan that has stopped spinning due to mechanical blockage .
4. Absolute Maximum Ratings
Supply Voltage, VDD
Output Current (Fault), IOUT
Operating Temperature Range, TA
Storage Temperature Range, TS
Maximun Junction Temp, TJ
(-0.3 to 18)V
500mA
-40 to 125°C
-55 to 165°C
150°C
Exceeding the absolute maximum ratings may cause permanent damage. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability.
