... Position detection monitoring function The MONI position detection monitoring pin open drian type. When the excitation position is in the initial position, the MONI output is placed in the ON state. (Refer to "(12) Examples of current waveforms in each of the excitation modes.") LV8713T Mode Internal regulator Standby ...

... When the OE pin is set High, the output is forced OFF and goes to high impedance. However, the internal logic circuits are operating, so the excitation position proceeds when the STEP signal is input. Therefore, when OE is returned to Low, the output level conforms to the excitation position proceeded by the STEP input. LV8713T Operating mode Normal operation ...

... I OUT = 1.0V/5 × 100%/0.5Ω = 400mA If, in this state, (ATT1, ATT2) is set to (H, H), IOUT will be as follows : I OUT = 400mA × 40% = 160mA In this way, the output current is attenuated when the motor holding current is supplied so that power can be conserved.
