Overview

The Intersil ISL54227IRUZ-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 device has two logic control input pins (OE and LP) to control the SPST switches.The ISL54227IRUZ-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 down-stream transceiver. It has an alarm indicator output pin (ALM) to indicate when the part is in the overvoltage condition.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 ISL54227IRUZ-T7A is available in 10 Ld 1.8mmx1.4mm µTQFN and 10 Ld 3mmx3mm TDFN packages. It operates over a temperature range of -40°C to +85°C.
