High-Speed USB 2.0 (480Mbps) DPST Switch with
Overvoltage Protection (OVP) and Dedicated Charger
Port Detection
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 3.5
Ω 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 processor when
entering a dedicated charging port mode of operation.
The ISL54227 is available in 10 Ld 1.8mmx1.4mm TQFN and
10 Ld 3mmx3mm TDFN packages. It operates over a temperature
range of -40°C to +85°C.
