clock generator circuit

The circuit illustrated in Figure 3-148 eliminates the requirement for a step-down transformer by utilizing a thyristor for brake control in small capacity asynchronous motor braking applications. Upon shutdown, the contactor KM1 releases, while contactor KM2 engages the brake...

A typical two high-pass filter circuit. A high-pass filter (HPF) is an electronic circuit that allows signals with a frequency higher than a certain cutoff frequency to pass through while attenuating signals with frequencies lower than the cutoff frequency. A...

This circuit detects the video signal from the VCR. When the VCR is powered on, the video signal is amplified by U3A to drive Q1, which activates K1. This setup eliminates the need to manually turn on and off...

This electronic liquid detector circuit diagram is based on the ULN2429 monolithic bipolar integrated circuit designed for detecting the absence or presence of many different types of liquids. The ULN2429 electronic liquid detector circuit can be used in automotive,...

This humidity-controlled switch circuit activates and deactivates an electrical load, such as a heater, based on the moisture content in the surrounding air. The humidity-controlled switch circuit employs a humidity sensor to detect changes in moisture levels in the environment....

The circuit supplies 1 A at +5 V from the -48 V supply commonly used in telephone equipment. More: The National Semiconductor LM2575 is a simple switching regulator. The circuit utilizes the National Semiconductor LM2575, which is a step-down (buck)...
