High-Speed USB 2.0 (480Mbps) Multiplexer with
Overvoltage Protection (OVP) and Overvoltage
Indicator Output
ISL54224
The Intersil ISL54224 is a single supply dual 2:1 multiplexer that
can operate from a single 2.7V to 5.25V supply. It contains two
SPDT (Single Pole/Double Throw) switches configured as a
DPDT. The part was designed for switching of USB data signals
in portable battery powered products.
The 6.5 switches were specifically designed to pass USB high
speed/full speed data signals. They have high bandwidth and
low capacitance to pass USB high speed data signals with
minimal distortion.
The ISL54224 has OVP circuitry on the D-/D+ com pins that
opens the USB in-line switches when the voltage at these pins
exceeds 3.8V (typ) or goes negative by -0.5V (typ). It isolates
fault voltages up to +5.25V or down to -5V from getting passed
to the other-side of the switch, thereby protecting the USB
transceivers.
The digital logic inputs are 1.8V logic compatible when operated
with a 2.7V to 3.6V supply. The ISL54224 has an open drain
OE/ALM pin that can be driven Low to open all switches and
outputs a Low when the OVP circuitry is activated. It can be used
to facilitate proper bus disconnect and connection when
switching between the USB sources.
The ISL54224 is available in 10 Ld 1.8mmx1.4mm TQFN and
10 Ld TDFN packages. It operates over a temperature range of
-40°C to +85°C.
