LTC4096/LTC4096X
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VDCIN = 5V, VUSBIN = 5V, RIDC = 1kΩ, RIUSB = 2kΩ, RITERM = 2kΩ unless
otherwise noted.

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 LTC4096 is guaranteed to meet the performance specifications
from 0°C to 85°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. See
Thermal Considerations.
Note 4: Supply current includes IDC and ITERM pin current (approximately
100µA 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 100µA 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
