High-Speed USB 2.0 (480Mbps) DPST Switch with
Overvoltage Protection (OVP) and Dedicated
Charger Port Detection
ISL54226
The Intersil ISL54226 is a single supply, dual SPST
(Single Pole/Single Throw) switch that is configured as a
DPST. It can operate from a single 2.7V to 5.25V supply.
The part was designed for switching or isolating a USB
high-speed source or a USB high-speed and full-speed
source in portable battery powered products.
The 3.5Ω SPST switches were specifically designed to
pass USB full speed and USB high-speed data signals.
They have high bandwidth and low capacitance to pass
USB high-speed data signals with minimal distortion.
The ISL54226 has OVP detection circuitry on the COM
pins to open the SPST switches when the voltage at
these pins exceeds 3.8V or goes negative by -0.45V. 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 down-stream transceiver.
The OE/ALM logic pin is an open drain input/output that
can be driven to open the switches or monitored to tell
when the part is in an overvoltage state.
The part has an interrupt (INT) output pin to indicate a
1 to 1 (high/high) state on the COM lines to inform the
µ
mode of operation.
The ISL54226 is available in 8 Ld 1.2mmx1.4mm
µTQFN and 8 Ld 2mmx2mm TDFN packages. It operates
over a temperature range of -40 to +85°C.
