The image depicts a proximity switch circuit that includes the HMC1001 Hall effect sensor, an operational amplifier (AMP04), and a light-emitting diode (LED). In this configuration, the operational amplifier functions as a comparator. When a magnet with a length...
Requiring only 10 µA of quiescent current, the circuit produces an ON-resistance of only 0.1 ohm. IC1 serves as a charge pump voltage converter to generate a 5V level, allowing analog switch IC2 to provide a 10V swing to...
A thermally controlled switch operates based on the surrounding temperature without human intervention, except during the construction of the electronic thermostat. This type of switch has numerous practical applications. For instance, it can activate an additional fan when the...
In today's environment, characterized by viruses and various threats from the Internet, it is essential to have assurance that a PC remains protected from infections. This circuit... To enhance the security of personal computers against viral threats and malware, a...
The following diagram illustrates the design of a 50W offline switching power supply circuit. This circuit is powered by a MOSFET, specifically the BUZ80A/IXTP4N8 for 220V AC input and the GE IRF823 for 110V AC input voltage. The output...
This circuit provides a regulated DC output with less than 100 mV of ripple for microprocessor applications. The required operating voltages are derived from a bleeder resistor network connected across the unregulated 28 V supply. The output of the...
