Refer to “Block Diagram” on page 7 and “Typical Application Schematics” on page 5. VIN = 4.5V to 60V, or VDD = 8V ±10%, C_VCC5V = 4.7µF, TA = -40°C to +125°C, Typical values are at TA = +25°C, unless otherwise specified. Boldface limits apply across the operating temperature range, -40°C to +125°C. (Continued) Parameter Symbol Test Conditions Min (Note 6)Typ Max (Note 6)Unit |
