4097f
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 LTC4097 is guaranteed to meet the performance specications
from 0°C to 85°C. Specications 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 60°C/W. See

ELECTRICAL CHARACTERISTICS The ● denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VDCIN = 5V, VUSBIN = 5V, HPWR = 5V, NTC = 0V, RIDC = 1kΩ, RIUSB = 2kΩ,
RITERM = 2kΩ unless otherwise noted.
Thermal Considerations.
Note 4: Supply current includes IDC and ITERM pin current (approximately
100A each) but does not include any current delivered to the battery
through the BAT pin.
Note 5: Supply current includes IUSB and ITERM pin current
(approximately 100A each) but does not include any current delivered to
the battery through the BAT pin.
Note 6: Guaranteed by long term current density limitations.
Note 7: VCC is greater of DCIN or USBIN
