The 556 Dual Monolithic timing circuit is an highly stable controllers capable of producing accurate time delays or
oscillation. The 556 is a dual 555. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other, sharing only VCC
and ground. The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200mA
In our application, especially in some outdoor applications, we often need to use the lithium battery, lithium battery charging problem is a need to solve the problem, we designed this mini lithium battery charging board.
Board size is very small , It can use external power supply, such as solar or USB power supply. It uses CN3065 - a single lithium...
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package.
