.. board). A hot-swap switch and carefully placed temperature sensors mitigate thermal issues by disconnecting system power when a temperature exceeds a safe limit. The circuit in Figure 1 uses a hot-swap switch to monitor overvoltage, ...
.. schematic diagram of the ultrasonic range finder device. As it is clear, the circuit consists of four main parts: sensor, power supply, MCU, and display. I explain each part separately. Figure 1. Schematic diagram of the ultrasonic range ...
.. a challenge to interface a resistive bridge sensor with an ADC receiving its power from a 5 V single-supply power source. Some applications require output-voltage swings from 0 V to a full-scale ...
.. can be powered from a supply ranging from 3 V to 6 V. It draws about 300 µA of average current at 5 V. It uses a low power op Amp as a pulse generator. A negative going pulse from that generator gates a power oscillator on for about ...
.. a phase shift between voltage and current and alter the sine-wave shape of the AC signal (resistive loads do not). The power factor of resistive loads is theoretically equal to 1. In this article, I introduce a circuit that can measure ...
