Overview

The Intersil ISL54226IRTZ-T7A 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 3.5ΩSPST 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 ISL54226IRTZ-T7A 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 downstream 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 µprocessor when entering a dedicated charging port mode of operation.The ISL54226IRTZ-T7A 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.
