Output current capability and IC power dissipation
between the output current and the IC power dissipation using PWM current control driving
a two-phase stepper motor, for different driving sequences:
●
HALF STEP mode (Figure 26) in which alternately one phase / two phases are
energized.
●
NORMAL DRIVE (FULL-STEP TWO PHASE ON) mode (Figure 27) in which two
phases are energized during each step.
●
WAVE DRIVE (FULL-STEP ONE PHASE ON) mode (Figure 27) in which only one
phase is energized at each step.
●
MICROSTEPPING mode (Figure 29), in which the current follows a sine-wave profile,
provided through the Vref 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 guarantee a safe operating junction temperature
(125 °C maximum).
