Programmable timers and oscillators are essential components of many electronic systems, from simple household appliances to sophisticated medical instruments. The 8N4Q001EG-1118CDI8 is an example of these devices, drawing on features to offer a versatile solution to timing problems.

Configuration and Features

The 8N4Q001EG-1118CDI8 is a CMOS programmable timer, with 16-pin ceramic package and 30KHz ~ 120KHz frequency range. It has a wide operating temperature range of -40oC to +85oC, and can be used in both oscillator and monostable modes. It also has a low-power standby current of 1.2uA, allowing for longer battery life.

Other features include selectable edge or level triggering, adjustable duty cycle, programmable output square wave duty cycle, and an integrated 3-bit frequency divider. This allows the 8N4Q001EG-1118CDI8 to be tailored to fit a wide range of applications.

Application and Working Principle

The 8N4Q001EG-1118CDI8 can be used for a variety of timing and oscillator needs. In particular, it is widely used in consumer, automotive and industrial electronics. It can be used to trigger alarms, initiate communication protocols, time operations, control power supplies, and more.

In oscillator mode, the 8N4Q001EG-1118CDI8 works by charging an internal capacitor through an external resistor. When the capacitor’s voltage reaches a predetermined level, it signals the timer to switch off the charging current and discharge the capacitor through an external resistor. As the capacitor is discharged, the voltage drops and eventually returns to the same predetermined level, causing the timer to switch the charge cycle back on again. This process repeats itself and produces an oscillating voltage output.

In monostable mode, the 8N4Q001EG-1118CDI8 works by charging an internal capacitor until a predetermined voltage is reached. When this level is reached, the timer switches off the charging current and maintains the voltage for a predetermined amount of time. When this time period has elapsed, the timer allows the capacitor to discharge, resulting in a single pulse output.

Summary

The 8N4Q001EG-1118CDI8 is an ideal choice for a wide range of programmable timer and oscillator needs. Such systems are vital for numerous tasks within consumer, automotive and industrial electronics, where accurate timing and frequency control is crucial. The 8N4Q001EG-1118CDI8 draws on a range of features to offer a flexible solution for such needs, with both oscillator and monostable modes, adjustable duty cycles, external resistors and more.
