Analog Devices ADM1072 Dual USB Power Controller Datasheet
The ADM1072 is a dual, logic-controlled P-channel switch designed to source up to 1A from supply voltages between 2.7V and 5.5V. It features low on-resistance (135mΩ) and includes built-in current limiting with selectable limits for Full Power Mode (500mA) and Standby Mode (100mA), compliant with USB 2.0 specifications.
The device incorporates protection mechanisms including short-circuit protection, thermal shutdown at +150°C, and undervoltage lockout between 2.0V and 2.6V. It is available in a small 16-pin QSOP package and is intended for use with desktop computers, notebook computers, palmtop computers, and hand-held instruments.
