Figure 14: Peak current 2Ip crossing the sense resistor RS in Full step drive. The phase sequence CCW

is: AB

→BA →AB → BA (4 Full Steps, 2 phase ON)

Figure 15: Peak current (2Ip/2 phase ON) and reduced peak current (1.4Ip/1 phase ON) crossing the sense

resistor RS in Half step drive. The phase sequence is: A

→AB → B → BA → A →AB →B → BA

(8 Half Steps, 1 phase ON and 2 phases ON alternatively)

Figure 16: Typical Application Circuit using 2 devices (Paralleled configuration): the max peak current

capability is of 2A/phase (RS = 0.25

Ω)
