Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LTC4011E 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.

Refer to the Applications Information section for details. This IC includes
overtemperature protection that is intended to protect the device during
momentary overload conditions. Junction temperature will exceed 125°C
when overtemperature protection is active. Continuous operation above
the specified maximum operating junction temperature may result in
device degradation or failure.

Note 4: All current into device pins is positive. All current out of device
pins is negative. All voltages are referenced to GND, unless otherwise
specified.
Note 5: These limits are guaranteed by correlation to wafer level
measurements.
Note 6: Output current may be limited by internal power dissipation. Refer
to the Applications Information section for details.
Note 7: Either TGATE V
Note 8: These limits apply specifically to the thermistor network shown in
Figure 5 in the Applications Information section with the values specified
for a 10k NTC (β of 3750). Limits are then guaranteed by specific V
voltage measurements during test.
