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 3.5 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 processor
when entering a dedicated charging port mode of operation.
The ISL54226 is available in 8 Ld 1.2mmx1.4mm TQFN and
8 Ld 2mmx2mm TDFN packages. It operates over a
temperature range of -40 to +85°C.
