Preliminary Technical Data  
ADM1072  
GEN ERAL D ESCRIPT ION  
FEATURES  
T he ADM1072 is a logic controlled, dual P-channel switch  
with low on resistance and a built-in current limiter, capable of  
sourcing up to 1A from supply voltages between 2.7V and  
5.5V. In addition to logic inputs that switch each channel on  
and off, the device has a standby input that switches the output  
current limit, making it ideal for use with USB peripherals. In  
normal operating mode and Standby mode the output current  
is typically limited to 500mA and 100mA respectively, as  
outlined by the USB2.0 Specification. T his allows the system  
power supply to be protected against short-circuits and surge  
currents in peripheral USB devices powered via the ADM1072.  
Over-current and over-temperature conditions are signalled by  
a fault output (FLT) for each channel.
