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