Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 CT O VOUT slew rate control
2 NC — Not internally connected
3 VIN I Switch input. Bypass this input with a ceramic capacitor to GND
4 VBIAS P Bias voltage. Power supply to the device
5 ON I Active high switch control input. Do not leave floating
6 GND GND Device ground
7 PG O Power good. Active high, open drain output. Tie to GND if not used
8 VOUT O Switch output
9
10
— VIN (Thermal Pad) I Switch input. VIN and thermal pad (exposed center pad) to alleviate thermal stress. See the Layout section for layout guidelines
