GLF Power Mux power multi-path management chip provides a better conversion solution for the circuit

Published:2022.03.11 Type:Product Information Share:

In daily life, many electronic devices, such as smart wearable devices, smart home devices, and industrial application devices, need to be equipped with rechargeable batteries to meet the application requirements of mobile use scenarios. It is necessary to optimize the design of circuit selection switching and power consumption issues. Power Mux Switch can play a key role in the seamless transition of circuits in circuit design.

Power Mux Switch

GLF's Power Mux Switch design is optimized for simplicity of installation and use. They are ideal for smart homes and other small systems where space and component count are critical. The GLF low-power power multi-path management chip is mainly aimed at the circuit structure with two power inputs and one output (typically, one USB and one lithium battery input), to provide the circuit switching function of automatic mode or manual mode. Compared with the traditional circuit structure built with discrete devices such as diodes and transistors, the power multi-path management chip has the characteristics of ultra-low quiescent current and impedance, optimized circuit structure, and convenient debugging by users.
