Output Current Capability and IC Power Dissipation
In Fig. 24, 25, 26 and 27 are shown the approximate relation between the output current and the IC power dis-
sipation using PWM current control driving a two-phase stepper motor, for different driving sequences:
– HALF STEP mode (Fig. 24) in which alternately one phase / two phases are energized.
– NORMAL DRIVE (FULL-STEP TWO PHASE ON) mode (Fig. 25) in which two phases are energized
during each step.
– WAVE DRIVE (FULL-STEP ONE PHASE ON) mode (Fig. 26) in which only one phase is energized at
each step.
– MICROSTEPPING mode (Fig. 27), in which the current follows a sine-wave profile, provided through
the V
ref
pins.
For a given output current and driving sequence 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 guar-
antee a safe operating junction temperature (125°C maximum).
