Output current capability and IC power dissipation
21/27

Output current capability and IC power dissipation
and the IC power dissipation using PWM current control driving two loads, for two different
driving types:
–
One full bridge ON at a time (Figure 19) in which only one load at a time is
energized.
–
Two full bridges ON at the same time (Figure 20) 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).
