Note 1:
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 specific performance limits. Electrical Characteristics state DC andAC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 2:
All voltages are measured with respect to the GND pin unless otherwise specified.
Note 3:
For operating at case temperatures above 25C, the LM4651 must be derated based on a 150C maximum junction temperature and a thermal resistance
of
θ
JA
= 62 C/W (junction to ambient), while the LM4652 must be derated based on a 150C maximum junction temperature and a thermal resistance of
θ
JC
=
2.0 C/W (junction to case) for the isolated package (TF) or a thermal resistance of
θ
JC
= 1.0C/W (junction to case) for the non-isolated package (T).
Note 4:
Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 5:
Machine Model, 220pF-240pF discharge through all pins.
Note 6:
The operating junction temperature maximum, T
jmax
is 150C.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
The LM4652TA package TA15A is a non-isolated package, setting the tab of the device and the heat sink at V potential when the LM4652 is directly
mounted to the heat sink using only thermal compound. If a mica washer is used in addition to thermal compound,
θ
CS
(case to sink) is increased, but the heat sink
will be isolated from V.
