5 / 28 page  PRODUCT SPECIFICATION FAN53180 REV. 1.0.0 6/10/03 5 Electrical Specifications1 (Vcc = 12V, TA = 0 °C to +85°C and FBRTN = GND, unless otherwise noted.) The • denotes specifications which apply over the full operating temperature range. Notes: 1. All limits at operating temperature extremes are guaranteed by design, characterization and statistical quality control. 2. Guaranteed by design – NOT tested in production.
