2.1.1.7 Pin 8 - J2 Configurations (3-Way Jumper)

If using separate I/O inputs, then J2 is used to configure pin 8 to: pullup to VIO, pullup to VCC or pulldown to GND. This pin can be pulled up to VIO by connecting a shunt to the J2A1 and J2A2 pins on J2, pulled up to VCC by connecting a shunt to the J2A2 and J2B pins, or pulled down to GND by connecting a shunt to the J2A2 and J2A3 pins on J1.

  • Mode Control input (S , STB, RS): if the device and application use pin 8 as mode control, set J2 to pulldown to GND for a normal or high-speed mode, (R11 is pre-installed with 0Ω resistor to GND for this purpose) or pullup to VCC/VIO for a silent or low-power standby mode.
  • Slope Control (RS): if the device and application use pin 8 as slope control, use the resistance to ground value to determine the slope of the driver output. R9 is left open for customers who want to install a resistance to ground and use slope mode.
  • Polarity Configuration (SW): if the device and application use pin 8 as polarity configuration, set J2 to pulldown to GND for normal polarity, or pullup to VIO for reverse polarity.
  • No Connection (NC): If the device and application require no use of pin 5, then leave open or pulled to GND.
