The SGM2591 is a single channel power distribution switch. The switch controlled by the EN pin operates from 2.5V to 6V supply voltage. It can be used in USB power distribution applications.
The SGM2591 has integrated current limit function to protect the upstream power supply from damage during over-current or short-circuit condition. It also has the function of over-temperature protection.
The device is designed with soft-start circuit to cope with inrush currents when large capacitive loads are connected. The nFAULT output will be asserted to low level during over-current, over-temperature or reverse voltage condition.
The SGM2591AD/BD/CD further reduces the total solution size by integrating a 50Ω pull-down resistor for output discharge when the switch is shut down by EN.
The SGM2591 is available in a Green SOT-23-5 package.
