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.

Power Switch/Driver 1:1 N-Channel 3.8A 6-WQFN-HR (1.5x0.75) The TPS22995RZGR is a high-current, low ON-resistance load switch designed for power distribution and power sequencing applications. It features an integrated N-channel MOSFET capable of handling high load currents while maintaining minimal voltage drop. The device includes controlled rise time to reduce inrush current, making it suitable for sensitive power rails and battery-powered systems. It also integrates thermal shutdown and overcurrent protection, ensuring safe operation under fault conditions. Its compact package and low quiescent current make it ideal for portable and space-constrained designs. Key Features Ultra-low ON-resistance (R<sub>ON</sub>) Wide input voltage range High continuous output current capability Controlled slew rate for inrush current limiting Low quiescent current Thermal shutdown protection Reverse current blocking (when disabled) Active high enable pin (ON pin) Compact WQFN package Electrical Characteristics Input Voltage Range: 0.5 V to 5.5 V ON-Resistance (R<sub>ON</sub>): Typically ~5 mΩ (VIN = 5 V) Continuous Output Current: Up to 6 A (typical, PCB dependent) Quiescent Current: Typically < 10 µA Shutdown Current: Typically < 1 µA Enable Threshold Voltage: ~0.9 V (typical) Functional Description The TPS22995RZGR operates as a load switch that connects or disconnects a power supply to a load using an internal MOSFET controlled by an enable (ON) pin. When the ON pin is asserted high, the device turns on with a controlled rise time, limiting inrush current. When disabled, the switch turns off quickly and prevents reverse current flow from the output to the input. Integrated protection features such as thermal shutdown ensure reliability during abnormal operating conditions.
