In 

 and 

 are shown the approximate relation between the output current 

and the IC power dissipation using PWM current control driving two loads, for two different 
driving types:


One full bridge ON at a time (

) in which only one load at a time is energized.



Two full bridges ON at the same time (

) in which two loads at the same time 

are energized.

For a given output current and driving type the power dissipated by the IC can be easily 
evaluated, in order to establish which package should be used and how large must be the 
on-board copper dissipating area to guarantee a safe operating junction temperature 
(125 °C maximum).
