Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The LTC4010E 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: Operating junction temperature T_J (in °C) is calculated from the
ambient temperature T_A and the total continuous package power
dissipation P_D (in watts) by the formula:
T_J = T_A + θ_JA • P_D
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 are positive. All current out of device
pins are negative. All voltages are referenced to GND, unless otherwise
specified.
Note 5: Output current may be limited by internal power dissipation. Refer
to the Applications Information section for details.
Note 6: Either specified output may apply for 7.5V < V_CC < 9V.
Note 7: These limits apply specifically to the thermistor network shown in
Figure 5 in the Applications Information section and are guaranteed by
specific V_TEMP voltage measurements during test.
