5 / 11 page  © 2006 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN7313 Rev. 1.0.0 5 Electrical Characteristics For typical values, TA=25°C and VIN=18V. For min./max. values, TA is the operating ambient temperature range with -25°C ≤ TA ≤ 85°C and 4.5V ≤ VIN ≤ 18V, unless otherwise specified. Specifications to -25°C ~ 85°C are guaranteed by design based on final characterization results. Notes: 3. These parameters, although guranteed, are not 100% tesed in production. 4. These parameters, although guranteed, are tested in only EDS test. Symbol Characteristics Test Condition Min. Typ. Max.
