Electrical Characteristics (continued)
(VSUP = VPWR = 3.7V, TJ = -40°C to 85°C, Typical Application Circuits, typical values are at TJ = 25°C unless otherwise specified. Limits over the specified operating temperature and supply voltage range are guaranteed by design and characterization, and production tested at room temperature only. )
