Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not
apply when operating the device beyond its specified operating ratings.
Note 2:
The junction temperature is internally limited by a thermal shutdown circuit. The maximum power dissipation is a function of
T
JMAX
,
θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is P
D
= (T
JMAX
- T
A
) /
θ
JA
. If this dissipation
is exceeded, the die temperature will rise above 150
°
C, and the MIC4807 will go into thermal shutdown.
Note 3:
All outputs are off when
OUTPUT ENABLE
is pulled low.
Note 4:
All outputs are turned on during this test.
Note 5:
Pulse testing is used to avoid thermal shutown.
Note 6:
Minimum and Maximum limits are tested and 100% guaranteed over the temperature range specified. Typicals are measured
at 25
°
C and represent the most likely parametric norm.
