Note 1: Absolute Maximum Ratings
are limits beyond which damage to the device may occur.
Operating ratings
are conditions under which the device operates
correctly. The gaurnteed specifications apply only for the listed test conditions. Some performance characteristics may degrade when the part is not operated under
listed conditions.
Note 2:
If BOOT voltage exceeds this value, the ESD structure will degrade.
Note 3:
Maximum allowable power dissipation is a function of the maximum junction temperature, T
, the junction-to-ambient thermal resistance,
θ
, and the
ambient temperature, T
. The maximum allowable power dissipation at any ambient temperature is calculated using: P
= (T
-T
) /
θ
. The junction-to-
ambient thermal resistance,
θ
, for LM2724A is 172C/W. For a T
of 150C and T
of 25C, the maximum allowable power dissipation is 0.7W. The
θ
JA
, for
LM2724A LLP package is 39C/W. For a T
JMAX
of 150C and T
A
of 25C, the maximum allowable power dissipation is 3.2W.
Note 4:
ESD machine model susceptibility is 200V.
Note 5:
If the positive pulse width at IN pin is below this value but above t
on_min2
, the pulse is internally stretched to t
on_min1
, so the HG width will be a constant
value.
Note 6:
If the positive pulse width at IN pin is below this value but above t
on_min3
, then HG stops responding while LG still responds to the pulse.
Note 7:
If the positive pulse width at IN pin is below this value, the pulse will be completely ignored. Neither HG or LG will respond to it.
Note 8:
If the negative pulse width at IN pin is below this value but above t
off_min2
, then LG stops responding while HG still responds.
Note 9:
If the negative pulse width at IN pin is below this value, the pulse will be completely ignored. Neither HG or LG will respond to it.
