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 limit is 100mA.
The ADM1072 is a logic-controlled dual P-channel switch designed for USB 2.0 applications, featuring supply steering between a main power source and a standby source. It is capable of sourcing up to 1A in full power mode and 100mA in standby mode, protecting against short circuits and surge currents in USB peripherals.
The device includes built-in protection features such as short-circuit protection, thermal shutdown, and undervoltage lockout. It operates with supply voltages between 2.7V and 5.5V and is available in a 16-pin QSOP package.
