The SGM2590 and SGM2590D 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 SGM2590 and SGM2590D integrate 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 SGM2590D further reduces the total solution size by integrating a 47Ω pull-down resistor for output discharge when the switch is shut down by EN.
SGM2590 and SGM2590D are available in a Green SOT-23-5 package.
