- EDN Under certain conditions, ESD events can damage digital circuits by causing latch-up. For example, when ESD triggers them, parasitic transistors normally formed as parts of a CMOS device can behave as an SCR (silicon-controlled rectifier). Once ...12-10-2020
- You sometimes need to know whether a resistance exceeds a preset limit. The continuity tester in Figure 1 lets you determine that fact for resistances of 0.5 Ω to 10 kΩ. The heart of the circuit is the transistor pair comprising Q 1 and ...21-07-2020
- William Lepkowski EDN Many low-dropout voltage regulators include an enable-input pin that can also serve as an inexpensive alternative to a voltage-supervisor IC. Although the enable pin normally serves as a means of shutting down the ...12-06-2020
- A traditional method of driving a low- to medium-power permanent-magnet dc motor involves using four MOSFET or bipolar transistors in an H-bridge configuration. For example, in Figure 1, the motor connects between collector pairs C 1 and C 2 and C ...03-06-2020
- The need for a compact telemetry system poses a challenge for designing a small, light, low-component-count system. Interfacing serial data from the microprocessor is also difficult because most low-cost RF transmitters do not accept dc levels at ...18-04-2020
- This project is based on STK984-090A from ON Semiconductor which is a fully-integrated inverter with current rating 20 A and supply voltage 40 V DC (Figure 1). It has been designed to drive the Brushless DC Motors (BLDC) and permanent magnet ...17-04-2020
- Aaron Lager EDN Using LEDs has gained popularity as a method of saving power for general-purpose lighting, but an efficient method for driving them has also become a necessity. For example, Lumileds' Luxeon devices create lighting effects or ...01-04-2020
- The basic VFC (voltage-to-frequency converter) in Figure 1 comprises an integrator (IC 1 ) and a Schmitt-trigger circuit (IC 2 ). The integrator converts the dc input voltage, V IN , to a linear voltage ramp, and the Schmitt trigger sets the limits ...06-03-2020
- Many improvements to the follower circuit have been proposed over the years. The White cathode follower doubles the output current and makes the transfer function more linear. [ 1 ] Adding a common-base amplifying stage (current follower) ...24-12-2019
- T A Babu EDN This flasher/beacon circuit can be employed as a distress signal on highways, a direction pointer for parking lots, hospitals, and hotels, etc. The circuit uses a power LED, and provides more light than a typical incandescent lamp ...02-11-2019
