1-2-1 2-Phase Stepper Motor Unipolar Driver ICs
SLA7060M/SLA7061M/SLA7062M
1-2 Phase to 4W 1-2 Phase Excitation Support, Built-in Sequencer
sFeatures
• Main supply voltage V
BB
: 46V (max), 10 to
44V recommended
• Logic supply voltage V
DD
: 3.0 to 5.5V support
• Lineup of output current I
O
: 1A, 2A, 3A
(maximum set current)
• Supporting the clock-input-method micro-step
drive (built-in sequencer)
• 1-2 phase excitation to 4W 1-2 phase
excitation support
• Self-excitation PWM current control method
• Built-in synchronous chopping function to
prevent the audible motor noise in the hold
state
• ZIP type 21-Pin mold package (SLA package)
