Note 1: Absolute Maximum Ratings are those values beyond which the life of the device may be impaired.  
Note 2: The EUP8054 are guaranteed to meet performance specifications from 0to 70. Specifications over the -40to 85℃  
operating temperature range are assured by design, characterization and correlation with statistical process controls.  
Note 3: See Thermal Considerations.  
Note 4: Supply current includes PROG pin current (approximately 100µA) but does not include any current delivered to the battery  
through the BAT pin (approximately 100mA).  
Note 5: This parameter is not applicable to the EUP8054X.  
Note 6: I TERM is expressed as a fraction of measured full charge current with indicated PROG resistor.
