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.

6 Uses0 StarsVNI2140J
Power Switch/Driver 1:1 N-Channel 500mA PowerSSO-12 8-channel protected high-side 12 V output switch IC The VNI2140J is a monolithic device designed using STMicroelectronics' VIPower technology. The device drives two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in cases of shorted-load, and built-in thermal shutdown protects the chip from damage due to overtemperature and short-circuit. In overload conditions, channel turns OFF and ON automatically to maintain the junction temperature between TTSD and TR. If the case temperature reaches TCSD, the overloaded channel is turned OFF and restarts only when case temperature decreases down to TCR. In order to avoid high-peak current from the supply, when more than one channel is overloaded the TCSD restart is not simultaneous. Non overloaded channels continue to operate normally. The open-drain diagnostics output indicates overtemperature conditions and open-load in OFF-state. Features • Nominal current: 0.75 A per channel • Shorted-load protections • Junction overtemperature protection • Case overtemperature protection for thermal independence of the channels • Thermal case shutdown restart not simultaneous for the various channels • Protection against loss of ground • Current limitation 1 A per channel • Undervoltage shutdown • Open-load in OFF-state and short to VCC detection • Open-drain diagnostic outputs • 3.3 V CMOS/TTL compatible inputs • Fast demagnetization of inductive loads • Conforms to IEC 61131-2 Applications • Programmable logic control • Industrial PC peripheral input/output • Numerical control machines #VNI2140J #STMicroelectronics #VIPower #HighSideSwitch #SolidStateRelay #PowerManagement #IndustrialAutomation #PLC #LoadDriver #PowerSSO12
