Figure 7-9. Quad-Level Input Pin Diagram

Figure 7-10 shows the input structure for STEP, DIR and nSLEEP pins.

Figure 7-10. Logic-Level Input Pin Diagram

7.3.8.1 nFAULT Pin

The nFAULT pin has an open-drain output and should be pulled up to a 5 V, 3.3 V or 1.8 V supply. When a fault

is detected, the nFAULT pin will be logic low. nFAULT pin will be high after power-up. For a 5 V pullup, the

nFAULT pin can be tied to the DVDD pin with a resistor. For a 3.3 V or 1.8 V pullup, an external supply must be

used.

Figure 7-11. nFAULT Pin

• The STL_REP pin has open-drain output and must be pulled up to a 5 V, 3.3 V or 1.8 V supply. When a stall

fault is detected, the STL_REP pin will be logic high. After a successful stall threshold learning, STL_REP pin

is pulled low. The STL_REP pin can also be used as an input. When pulled low externally, stall fault reporting

is disabled. For a 5 V pullup, the STL_REP pin can be tied to the DVDD pin with a resistor. For a 3.3 V or 1.8

V pullup, an external supply must be used.
