- Ken YangFor the heating and cooling elements common in industrial systems, resistance is not a fixed quantity. These elements include such devices as positive-temperature-coefficient heaters and thermoelectric coolers. Their resistance can change more than ...Jan 20, 2025
- Using the MAX4373 high-side current-sense amplifier, a circuit can be designed with a voltage range to 28 V. All that is needed is a general-purpose NPN transistor. The latching-comparator output (COUT1) on the MAX4373, a high-side current-sense ...Jan 13, 2025
- Dale LitwhilerYou can use the simple sensor circuit in Figure 1 to remotely monitor the level of liquid water in a vessel such as a swimming pool. The LMC555 sensor oscillator provides an output-signal frequency that is a function of the water level. This signal ...Sep 2, 2024
- Ken YangIncluded among the many applications for pulse-width modulation (PWM) are voltage regulation, power-level control, and fan-speed control. A PWM circuit for such systems can be implemented with three op amps on a single quad-op-amp chip (Fig. 1). ...Aug 1, 2024
- Alfredo Saab Steve LoganAs the latest generation of new LEDs achieves higher levels of power and efficiency, use of these devices extends to new areas, such as flashlights and vehicular applications. High-power LEDs are finding use even in ambient lighting, long the sole ...Mar 20, 2024
- Steve CaldwellDesigners often use relays as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. However, the power dissipation in a relay coil may render the device unattractive in ...Feb 2, 2023
- Arthur Harrison Joseph SternIn the proximity detector of Figure 1, a 4-in.-sq piece of copper-plated pc board serves as an antenna that forms one plate of a capacitor. An approaching (grounded) person serves as the other plate, producing a capacitance value of 2 to 5 pF that ...Dec 29, 2022
- Tim HerklotsThe standard boost converter in Figure 1 uses not only IC 1 , C 1 , L 1 , D 1 , and C 2 to generate a main 5 V output, but also additional small, low-cost components to provide two auxiliary supply rails of 10 and 5 V. These auxiliary outputs are ...Dec 21, 2022
- Rajkumar SharmaA rechargeable battery’s load should be disconnected at the point of complete discharge, to avoid a further (deep) discharge that can shorten its life or destroy it. Because a battery’s terminal voltage recovers when you disconnect the ...Dec 16, 2022
- Donald SchelleMechanical push-pushbutton switches (also known as alternate-action or push-on/push-off switches) can be bulky and expensive. As an alternative, an electronic version uses a cheaper, NO (normally open), momentary-on switch (Figure 1). Figure 1. ...Dec 13, 2022
