GENERAL DESCRIPTION
The 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. This allows the system power supply to be protected against short-circuits and surge currents in peripheral USB devices powered via the ADM1072.
