DESCRIPTION
The Si4788CY is a p-channel MOSFET with a logic interface.
The control input is compatible with all types of logic down to
1.8 V. The switch can be used to control voltages from 1.8 V
to 5.5 V, and the logic input can be a lower voltage than the
power. The switch also incorporates reduced switching speed
to reduce inrush when switching loads with a high value of
capacitance. The Si4788CY is packaged in an 8-pin SOIC
package and rated for the commercial temperature range of
0 to 85_C
