FUNCTIONAL DESCRIPTION
The total power dissipation available is dependent on the
number of outputs enabled at any one time. At 25°C the
R
DS(ON)
in 450 m
with a coefficient of 6500 ppm/°C. For the
junction temperature to remain below 150°C, the maximum
available power dissipation must decrease as the ambient
temperature increases.
Figure 23
depicts the per output limit
of current at ambient temperatures necessary when one,
four, or eight outputs are enable ON.
Figure 25
illustrates
how the R
DS(ON)
output value is affected by junction
temperature.
