8.3.3 Pin Diagrams
Figure 37 shows the input structure for the logic-level pins, INHx, INLx, ENABLE, nSCS, SCLK, and SDI.
Figure 37. Logic-Level Input Pin Structure Figure 38 shows the structure of the four level input pins, MODE and GAIN, on hardware interface devices. The input can be set with an external resistor.
Figure 38. Four Level Input Pin Structure Figure 39 shows the structure of the seven level input pins, IDRIVE and VDS, on hardware interface devices. The input can be set with an external resistor.
Figure 39. Seven Level Input Pin Structure Figure 40 shows the structure of the open-drain output pins nFAULT and SDO. The open-drain output requires an external pullup resistor to function correctly.
