Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 VIN I Switch input. Place ceramic bypass capacitor(s) between this pin and GND. See the Detailed Description section for more information.
2 GND — Device ground.
3 ON I Active high switch control input. Do not leave floating.
4 CT O Switch slew rate control. Can be left floating. See the Feature Description section for more information.
5 QOD O Quick Output Discharge pin. This functionality can be enabled in one of three ways.
  • Placing an external resistor between VOUT and QOD
  • Tying QOD directly to VOUT and using the internal resistor value (RPD)
  • Disabling QOD by leaving pin floating
See the Quick Output Discharge (QOD) section for more information.
6 VOUT O Switch output.
