What is a 555 timer and how does it work?




Before we go any further, let us briefly explain what a 555 timer is and how it works. A 555 timer is a type of integrated circuit (IC) that can be used to generate timed pulses or oscillations. It was invented in 1971 by Hans R. Camenzind and has become one of the most widely used ICs in electronic projects. It is cheap, easy to use, and versatile, as it can be configured in different modes of operation for various applications.


The basic structure and function of a 555 timer




A 555 timer consists of two comparators, a flip-flop, a discharge transistor, and a resistor network. These components are arranged as shown in the following diagram:


The 555 timer has eight pins that are connected to external components as follows:


PinNameFunction


1GNDGround (0 V)


2TRIGTrigger input


3OUTOutput


4RSTReset input


5CTRLControl voltage input


6THRThreshold input


7DISDischarge output


8VCCSupply voltage (+5 V to +15 V)


The basic function of a 555 timer is to compare the voltages at the trigger and threshold inputs with two reference voltages that are set by the resistor network. The reference voltages are 1/3 VCC and 2/3 VCC, where VCC is the supply voltage. The output of the comparators is fed to the flip-flop, which controls the state of the output and the discharge transistor. The output can be either high (+VCC) or low (0 V), depending on the mode of operation of the 555 timer.


The different modes of operation of a 555 timer




A 555 timer can be configured in three main modes of operation: monostable, astable, and bistable. Each mode has its own characteristics and applications, as explained below.


Monostable mode




In monostable mode, also known as one-shot mode, the 555 timer produces a single pulse of a fixed duration when triggered by a low voltage at the trigger input. The duration of the pulse is determined by the values of an external resistor and capacitor connected to the threshold and discharge pins. The following diagram shows the circuit and waveform for monostable mode:


The formula for calculating the pulse duration (T) in monostable mode is:


T = 1.1 x R x C


where R is the resistance in ohms, C is the capacitance in farads, and T is the time in seconds.


In monostable mode, the output remains low until a trigger pulse is applied to the trigger input. This causes the comparator to output a high signal, which sets the flip-flop and makes the output go high. At the same time, the discharge transistor turns off, allowing the capacitor to charge through the resistor. When the capacitor voltage reaches 2/3 VCC, the threshold comparator outputs a low signal, which resets the flip-flop and makes the output go low. The discharge transistor also turns on, discharging the capacitor through it. The output remains low until another trigger pulse is applied, and the cycle repeats.


Monostable mode is useful for creating timers, delays, pulse extenders, pulse detectors, etc.


Astable mode




In astable mode, also known as free-running mode, the 555 timer produces a continuous stream of pulses with a variable frequency and duty cycle. The frequency and duty cycle are determined by the values of two external resistors and one capacitor connected to the threshold, trigger, and discharge pins. The following diagram shows the circuit and waveform for astable mode:


The formulas for calculating the frequency (f) and duty cycle (D) in astable mode are:


f = 1.44 / (R1 + 2R2) x C


D = (R1 + R2) / (R1 + 2R2) x 100%


where R1 and R2 are the resistances in ohms, C is the capacitance in farads, f is the frequency in hertz, and D is the duty cycle in percentage.


In astable mode, the output alternates between high and low states at a regular interval. The capacitor charges and discharges through the resistors, creating a sawtooth waveform at the threshold and trigger inputs. When the capacitor voltage reaches 2/3 VCC, the threshold comparator outputs a low signal, which resets the flip-flop and makes the output go low. The discharge transistor also turns on, discharging the capacitor through R2. When the capacitor voltage drops below 1/3 VCC, the trigger comparator outputs a high signal, which sets the flip-flop and makes the output go high. The discharge transistor turns off, allowing the capacitor to charge through R1 and R2. The cycle repeats indefinitely until the power is turned off.


Astable mode is useful for creating oscillators, clocks, tone generators, blinkers, etc.


Bistable mode




In bistable mode, also known as flip-flop mode, the 555 timer acts as a simple memory device that can store one bit of information. It has two stable states: high or low. The state of the output can be changed by applying a high voltage to either the trigger or the reset input. The following diagram shows the circuit and waveform for bistable mode:


In bistable mode, there is no external resistor or capacitor connected to the threshold or discharge pins. The trigger input is connected to a push button that pulls it low when pressed. The reset input is connected to another push button that pulls it low when pressed. The output is connected to an LED that indicates its state.


In bistable mode, the output remains in its previous state until a change is triggered by either the trigger or the reset input. When a high voltage is applied to the trigger input, the comparator outputs a high signal, which sets the flip-flop and makes the output go high. The LED turns on, indicating that the output is high. When a high voltage is applied to the reset input, the comparator outputs a low signal, which resets the flip-flop and makes the output go low. The LED turns off, indicating that the output is low. The output remains in its current state until another change is triggered by either input.


Bistable mode is useful for creating switches, latches, memory devices, etc.

PWM controller




A PWM controller is a circuit that uses a 555 timer in astable mode to generate a pulse-width modulated (PWM) signal. A PWM signal is a type of signal that has a variable duty cycle, which means that it can switch between high and low states at different ratios. The duty cycle can be adjusted by changing the values of the resistors and capacitor or by applying a control voltage to the control input. The following diagram shows the circuit and waveform for a PWM controller:


A PWM controller can be used for controlling the speed of motors, the brightness of LEDs, the power of heaters, etc.
