DESCRIPTION
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 complies with the release of the PC Card standard
by suppling 0 V, 12 V, and VCC to the Vpp output and 0 V, 3.3 V,
and 5 V to the VCC output. The VCC ramp time is user
programmable with an external capacitor connected to the SR
pin.
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 5 V.
The PC Card switch is packaged in a narrow body SO-16
package and is rated over the industrial temperature range
−40 to 85_C.
The Si9712 is available in both standard and lead (Pb)-free
packages.
