SGM2595D中文资料Power Distribution Switch数据手册SGMICRO规格书

描述 Description

The SGM2595D 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 SGM2595D 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 SGM2595D 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 SGM2595D is available in Green MSOP-8 and SOT-23-5 packages.
