Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC4063EDD is 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 correctly solder the Exposed Pad of the package to the
PC board will result in a thermal resistance much higher than 40°C/W.
Note 4: Supply current includes PROG pin current and IDET pin current
(approximately 100μA each) but does not include any current delivered to
the battery through the BAT pin (approximately 100mA).
Note 5: Does not include LDO supply current.
Note 6: The LDO is partially powered from V CC , thus reducing the supply
current from the BAT pin.
Note 7: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions.
Overtemperature protection will become active at a junction temperature
greater than the maximum operating temperature. Continuous operation
above the specified maximum operating junction temperature may impair
device reliability.
Note 8: Defined by long term current density limitations.
