Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. 8. SYNC pulse width is the greater of this value or the CT discharge time. 9. This is the maximum duty cycle achievable using the specified values of RTC, RTD, and CT. Larger or smaller maximum duty cycles may be obtained using other values for these components. See Equations 2 through 4. Electrical Specifications Recommended operating conditions unless otherwise noted. Refer to “Functional Block Diagram” on page 2 and page 3 and Typical Application Schematics on page 4 to page 6. 9V < VDD < 20 V, RTD = 51.1kΩ, RTC = 10kΩ, CT = 470pF, TA = -40°C to +105°C, Typical values are at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +105°C (Continued) PARAMETER TEST CONDITIONS MIN (Note 7) TYP MAX (Note 7) UNITS |
