Note 2: The LP4062 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 LP4062. Note 6: ITERM is expressed as a fraction of measured full charge current with indicated PROG resistor. |
