Switches
A switch is a device that allows electricity to flow through a circuit by completing or interrupting the connection. It is a common component in electrical and electronic systems and is used in a variety of applications, such as controlling the flow of electricity in a circuit, turning devices on and off, and routing electrical signals. One of the primary use cases for switches is to control the flow of electricity in a circuit. This can be done by manually flipping the switch or by using a control mechanism, such as a timer or a sensor. Another common use for switches is to turn devices on and off. This can be done using a switch that is built into the device or by using a separate switch that is connected to the device. In addition to these basic use cases, switches can also be used to route electrical signals. For example, a switch can be used to route a signal from one device to another or to direct a signal to a specific circuit or component. If you're looking for a wide variety of switches for your projects, flux.ai has the world's largest community-driven public library of them. The library includes footprints, symbols, datasheets, and simulation models for a wide range of switches, making it easy to find the right switch for your needs.

The devices integrate low-loss power switches and provide high efficiency, low heat, and fast battery charging in a small solution size. The reverse buck has true load disconnect and is protected by an adjustable output current limit. The devices are highly flexible and programmable through I2C configuration or autonomously through resistor configuration. The battery charger includes the Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up smoothly when an input source is available even when the battery is deeply discharged (dead battery) or missing. For battery safety/authentication reasons, the ICs can be configured to keep charging disabled, and allow the DC-DC to switch and regulate the SYS voltage. The system processor can later enable charging using I2C commands as appropriate. Alternatively, the ICs can be configured to automatically start charging. #CommonPartsLibrary #IntegratedCircuit #PowerManagement #MAX77961
