Timers and RTCs
Timers and Real-Time Clocks (RTCs) are electronic devices that are used to measure time or keep track of the current time. They can be found in a wide range of applications, including computers, phones, and appliances. Timers are used to trigger an action after a specific period of time has elapsed. They can be used to control the duration of an event, or to schedule tasks to be performed at a later time. RTCs, on the other hand, are used to maintain accurate time even when the device is powered off. They are often used in devices that need to keep track of the current time and date, such as alarm clocks and smart thermostats. If you're looking for high-quality timers and RTCs for your electronic projects, you should check out Flux.ai.

Electronic Fuse Regulator High-Side 10A 10-VQFN-HR (2x2) The TPS25981xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short circuits, voltage surges and excessive inrush current. Output slew rate and inrush current can be adjusted using a single external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current (during startup) or breaking the circuit (during steady-state). The overcurrent protection threshold as well as the transient overcurrent blanking timer are useradjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2-mm × 2-mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint.
