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 0℃ to 70℃. Specifications over the -40℃ to 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
