The NE555PWE4 is a programmable timer IC (integrated circuit) with oscillator and delay circuitry. It was designed to provide a wide range of timing functions within a wide variety of sets and field applications. The NE555PWE4 offers an extensive range of features such as high-frequency oscillator, precision timing range of 10 to 100 microseconds, linearity of timing over temperature and operating voltage, and operation from a single supply from 4.5 V to 18 V. It can be used to control various activities in a wide range of devices from a heating element to a fan speed control.
Features
The NE555PWE4 features programmable timers and oscillators for precise timing applications. It features a fast responding, high accuracy, low-power design with a wide range of timing options including coarse adjustment, minimum delay and reset delays. It also offers adjustable accuracy over temperature and voltage variations. The NE555PWE4 also has an active-low reset input, Schmitt-trigger input, and a temperature-compensated output.Design
The NE555PWE4 is designed with a two-stage construction comprising of two 555 timers, an output amplifier, and a reset circuit. The two 555 timers are configured in a start/stop mode with an active low reset. When the reset input is low, both timers are disabled. When the reset input is high, the timer is activated and the timing cycle begins. The first stage enables the oscillator and starts the timing cycle, while the second stage enables the output amplifier and triggers the delay timer when the preset time is reached. The NE555PWE4 has a single output amplifier that is used to control any load.Application fields
The NE555PWE4 has a wide range of applications in the fields of industrial automation, automotive, consumer products, test and measurement, and personal computer devices. It can be used in a variety of applications, such as:- Delay-on-Make, Delay-on-Break timer circuits
- Input amplifier for automotive sensors
- Time-delay relays
- Period measurement circuit
- Motor speed control
- Light dimmers
- Electronic thermostats
Working principle
The NE555PWE4 works with a two-stage timer configuration and is designed to provide a very versatile timing function. When the reset input is low, both timers are disabled. When the reset input is high, the timer is activated and the timing cycle begins. The first stage enables the oscillator and begins the timing cycle, while the second stage enables the output amplifier and triggers the delay timer when the preset time is reached.The timing cycle begins as soon as the reset input is high and the output of the first timer (the oscillator) becomes high. This signal is then fed to the reset input of the second timer and the second stage starts running; when the preset time is reached, the second timer will trigger the output and the cycle will repeat.The output of the NE555PWE4 can be programmed to stay on for a fixed amount of time or can be triggered to reset after a specific amount of delay time. The device offers a wide range of timing options, including coarse adjustment, minimum delay, and reset delays.Conclusion
The NE555PWE4 is a versatile IC with a wide range of applications in the field of industrial automation, automotive, consumer products, test and measurement, and personal computer devices. It offers adjustable accuracy over temperature and voltage variations and has a fast responding, high accuracy, low-power design. The two 555 timers are configured in a start/stop mode with an active low reset and the output can be programmed to stay on for a fixed amount of time or can be triggered to reset after a specific amount of delay time.The specific data is subject to PDF, and the above content is for reference
