Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 VIN I Switch input. Input bypass capacitor recommended for minimizing VIN dip. Must be connected to Pin 1 and Pin 2. See the Application and Implementation section for more information
2
3 ON I Active high switch control input. Do not leave floating
4 VBIAS I Bias voltage. Power supply to the device. Recommended voltage range for this pin is 2.5 V to 5.7 V. See the Application and Implementation section for more information
5 GND — Device ground
6 CT O Switch slew rate control. Can be left floating. See the Adjustable Rise Time section under Feature Description for more information
7 VOUT O Switch output
8
— Thermal Pad — Thermal pad (exposed center pad) to alleviate thermal stress. Tie to GND. See the Layout Example section for layout guidelines
