These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) All voltages are measured with respect to GND, unless otherwise noted.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not guarantee performance limits. For guaranteed specifications and test conditions, see the
Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4) When the input voltage (V
IN
) at any pin exceeds the power supplies (V
IN
< GND or V
IN
> V+), the current at that pin should be limited to
5 mA. Parasitic components and/or ESD protection circuitry are shown below for the LM96163's pins. Care should be taken not to
forward bias the parasitic diode, D2, present on pins D+ and D−. Doing so by more than 50 mV may corrupt temperature
measurements.
(5) Thermal resistance junction to ambient when attached to a 2 layer 4"x3" printed circuit board with copper thickness of 2oz. as described
in JEDEC specification EIA/JESD51-3 is 137°C/W. Thermal resistance junction to ambient when attached to a 4 layer 4"x3" printed
circuit board with copper thickness 2oz./1oz./1oz/2oz. and 4 thermal vias as described in JEDEC specification EIA/JESD51-7 is
40.3°C/W.
(6) Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin. Charged
Device Model (CDM) simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated
assembler) then rapidly being discharged.

design calculations.
(2) Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
(3) The accuracy of the LM96163 is guaranteed when using a typical thermal diode of an Intel processor on a 45 nm process, as selected
in the Remote Diode Model Select register. See Typical Performance Characteristics for performance with Intel processor on 65 nm or
90 nm process.
(4) Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is the product of the
internal power dissipation of the LM96163 and the thermal resistance.
