Si9712

The Si9712 combines low on-resistance with slow ramp time and smart switching for overall best performance in integrated PC Card interface switches.

The Si9712 operates off the 5-V supply and has built-in level shifting for gate drive. Internal logic protects against an external control input error that would short 5 V to the 3.3-V supply. This protection logic also allows the Si9712 to be configured for positive or negative control logic for compatibility with a variety of PC Card controllers. These control inputs are CMOS logic compatible and can be driven to 3.3 V or 5V.

The Si9712 complies with the release of the PC Card standard by suppling 0 V, 12 V, and V_CC to the V_pp output and 0 V, 3.3 V, and 5 V to the V_CC output. The V_CC ramp time is user programmable with an external capacitor connected to the SR pin.

The PC Card switch is packaged in a narrow body SO-16 package and is rated over the industrial temperature range −40 to 85.

The Si9712 is available in both standard and lead (Pb)-free packages.
