SGM25006数据手册SGMICRO中文资料规格书

描述 Description

The SGM25006 is a single channel power distribution switch. The switch operates from a wide range of 2.5V to 6.5V supply voltage, and is controlled by the nEN/EN pin. The rise time and fall time of the device are controlled internally to avoid inrush current.
An integrated charge pump biases the N-MOSFET switch in order to achieve a low switch RDSON. This device provides the adjustable current limit threshold between 500mA and 5A through the RILIM. If the load current is higher than the current limit threshold, the device will limit the output current to a safe level and enter into constant-current mode. Fault conditions such as over-current and over-temperature are indicated by the nFAULT pin.
The SGM25006 is available in a Green TDFN-3×3-8FL package.
