(Between VCC and BAT)

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LTC4059E/LTC4059AE are guaranteed to meet performance

specifications from 0

°C to 70°C. Specifications over the –40°C to 85°C

operating temperature range are assured by design, characterization and

correlation with statistical process controls.

Note 3: Failure to solder the exposed backside of the package to the PC

board ground plane will result in a thermal resistance much higher than

°C/W.

Note 4: The FET on-resistance is guaranteed by correlation to wafer level

measurements.
