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 LTC4010E is guaranteed to meet performance specifications
from 0°C to 70°C. Specifications over the 0°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: Operating junction temperature TJ (in °C) is calculated from
the ambient temperature TA and the total continuous package power
dissipation PD (in watts) by the formula:
TJ = TA + qJA PD
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
The l indicates specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 12V, BAT = 4.8V, GND = PGND = 0V, unless otherwise noted.

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 TGATE VOH may apply for 7.5V < VCC < 9V.
Note 7: These limits apply specifically to the thermistor network shown in
Figure 5 in the Applications Information section with a
b of 3750 and are
guaranteed by specific VTEMP voltage measurements during test.
Note 8: These limits are guaranteed by correlation to wafer level
measurements.
