ELECTRICAL CHARACTERISTICS
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

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.
