The SGM2593 and SGM2593D are single channel power distribution switches. The switch is controlled by the EN pin and operates from 2.5V to 6V supply voltage. It can be used in USB power distribution applications.
The device integrates programmable current limit 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 SGM2593D further reduces the total solution size by integrating a 47Ω pull-down resistor for output discharge when the switch is shut down by EN.
The SGM2593 and SGM2593D are available in Green TDFN-2×2-6AL and SOT-23-6 packages.
