Caution: VCC, RL, and the output level must be set for the size of the heat sink used so that the Pd max range is not exceeded.
*1.
When both channels are operating such that IO peak = 1.0A per channel is exceeded.
If the IC is operated such that IO peak = 1.0A per channel is not exceeded, the IC can be used in the range 5.5 to 20V (in the ranges where Pd max
is not exceeded) with a load of RL= 4 to 8.
