ISL54227
The Intersil ISL54227 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
device has two logic control input pins (OE and LP) to
control the SPST switches.
The ISL54227 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 ISL54227 is available in 10 Ld 1.8mmx1.4mm
µTQFN and 10 Ld 3mmx3mm TDFN packages. It
operates over a temperature range of -40 to +85°C.
