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

●
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).
