SGM2591 Power Distribution Switch
■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.
