Detailed Descriptions
The ISL43410 operates from a single 2V to 12V supply with
low ON-resistance (115
Ω) and high speed operation
(tON = 60ns, tOFF = 30ns). The ISL43410 is especially well
suited to portable battery powered equipment thanks to the
low operating supply voltage (2.0V), low power consumption
(3W), low leakage currents (5nA max), and the tiny MSOP
and QFN packaging. High frequency applications also benefit
from the wide bandwidth, and the very high OFF-isolation
(75dB) and crosstalk rejection (-85dB).
Supply Sequencing And Overvoltage Protection
With any CMOS device, proper power supply sequencing is
required to protect the device from excessive input currents,
which might permanently damage the IC. All I/O pins contain
ESD protection diodes from the pin to V+ and GND (see
Figure 8). To prevent forward biasing these diodes, V+ must
be applied before any input signals, and input signal
voltages must remain between V+ and GND. If these
conditions cannot be guaranteed, then one of the following
two protection methods should be employed.
Logic inputs can easily be protected by adding a 1k
Ω
resistor in series with the input (see Figure 8). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
produces an insignificant voltage drop during normal
operation.
This method is not applicable for the signal path inputs.
Adding a series resistor to the switch input defeats the
purpose of using a low rON switch, so two small signal
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 8). These
additional diodes limit the analog signal from 1V below V+ to
1V above GND. The low leakage current performance is
unaffected by this approach, but the switch resistance may
increase, especially at low supply voltages.
