Figure 7: Typical Application Diagram
Notes:
(1) All resistors are ± 5%, ¼ W
(2) C₁, C₂ minimum value is 2.7nF, maximum value is 10nF
(3) Depending on the application, the ESR value and working voltage of C₇ must be carefully chosen
(4) C₃ and C₄ must be close to pins VBB and GND
(5) C₅ and C₆ must be as close as possible to pins CPN, CPP, VCP, and VBB to reduce EMC radiation
(6) C₉ must be a ceramic capacitor to assure low ESR
12.0 Positioning Parameters
12.1 Stepping Modes
One of four possible stepping modes can be programmed:
• Half-stepping
• 1/4 micro-stepping
• 1/8 micro-stepping
• 1/16 micro-stepping
