CD4047BMG4 Application Field and Working Principle

CD4047BMG4 is a high-frequency astable/monostable flip-flop multivibrator and voltage-controlled oscillator (VCO) with a power-on reset capability. This device is a direct result of the continued development of Flip-flop devices in logic family. It provides various design options, such as low parts count, low-cost oscillators, and high performance monostable and astable timers.

Applications

The primary application of CD4047BMG4 is to provide a VCO with an adjustable frequency and duty cycle. It is widely used in applications such as frequency shifters, PWM controllers, remote controls, microwave ovens, medical instruments, and servo loop controllers. It also provides an alternative to 555 timers and CRO/Logic memory circuits. The device can be used as a versatile oscillator, monostable or a relaxation oscillator. The device features pulse width modulation with outputs of up to 15V to drive relays, motors and buzzers.

Working Principle

The CD4047BMG4 operates as a flip-flop multivibrator with two complementary outputs. It consists of two flip-flops, one master and one slave, with both stages coupled together. The master stage is triggered by the pins labeled A1 and B1 and the slave stage is triggered by pins labeled A2 and B2. When A2 is low, the slave trigger pulse is generated and the output at pin 7 (Q) is low. When B2 is high, the slave trigger pulse is generated and the output at pin 7 (Q) is highWhen the master trigger A1 and B1 pins are both low, then the output at pin 6 (Qbar) is high and the output at pin 7 (Q) is low. When the master trigger A1 and B1 pins are high, the output at pin 6 (Qbar) is low and the output at pin 7 (Q) is high. This flip-flop action can be used to create a frequency oscillator, astable or monostable or a voltage-controlled oscillator. The oscillator circuit consists of a voltage divider network and capacitor, which sets the frequency and duty cycle. The capacitor is discharged via the B1 Trigger pin, charging via the C pin and allowed to settle via the C-ES pin. This allows the circuit to control its own feedback loop, providing adjustment of both frequency and duty cycle.

Conclusion

In conclusion, the CD4047BMG4 is a versatile flip-flop multivibrator and voltage-controlled oscillator which provides design options in the form of low-part count, low-cost oscillators, and high-performance monostable and astable timers. The device features pulse width modulation capabilities and outputs up to 15V to drive relays, motors and buzzers. With its wide range of applications and ease of use, the CD4047BMG4 is an ideal choice for a number of applications.
