Hi, in today's video I'll show you how to make a High Current PWM Driver based on the NE555 timer IC and the IRF3205 Power MOSFETs.
Overview
The 555 timer IC (integrated circuit) is a versatile and widely used device in the field of electronics. Introduced in 1972 by Signetics (now a part of ON Semiconductor), the 555 timer has become one of the most popular ICs due to its flexibility and ease of use. The IC is commonly employed in various applications such as timers, pulse generators, oscillators, and voltage-controlled oscillators.
Here are some key features and aspects of the 555 timer IC:
1. Operating Modes:
- Monostable Mode: In this mode, the 555 timer functions as a one-shot pulse generator. It produces a single pulse of a specified duration when triggered.
- Astable Mode: In this mode, the 555 timer operates as an oscillator, generating a continuous square wave output. It is commonly used for applications like LED flashers and tone generators.
- The 555 timer consists of two voltage comparators, an SR flip-flop, a discharge transistor, and a resistor divider network. These components work together to create the various operating modes.
- The 555 timer typically has eight pins: VCC (power supply), GND (ground), TRIG (trigger), OUT (output), RESET, CTRL (control voltage), THRS (threshold), and DISCH (discharge).
- External components such as resistors and capacitors are connected to these pins to set the timing characteristics of the IC.
- Precision Timing: The 555 timer is widely used in applications requiring accurate and adjustable timing intervals, such as pulse width modulation (PWM).
- Pulse Generation: It is commonly employed to generate pulses for various purposes, including triggering other devices or controlling motors.
- Oscillation: The astable mode of the 555 timer is frequently utilized in electronic circuits that require a stable square wave oscillator.
- Over the years, various versions and derivatives of the 555 timer IC have been developed, including the CMOS version (such as the 7555) with lower power consumption.
- The 556 is a dual 555 timer IC, containing two 555 timers in a single package.
- The 555 timer has some limitations, such as its inability to provide very high-frequency outputs and its sensitivity to supply voltage variations.
