21 / 179 page  Electrical Characteristics (IN = 4.2V to 18V, TA = -40°C to +85°C, typical values are TA = +25°C, see the schematic in the Functional Diagram. Limits are 100% tested at TA = +25°C. Limits over the operating temperature range and relevant supply voltage range are guaranteed by design and characterization.)
