    TIDA-00839?SYS-null-null-findchips-refdes-rd-null-wwe: Magnetic tampering can paralyze any transformer in an energy measurement system, which may potentially lead to the system being unable to be powered properly or unable to correctly register the energy consumed by a load. This design implements a Class 0.2 three-phase energy measurement system that detects magnetic tampering using hall sensors. Magnetic tamper detection is enabled when running from both main and backup power sources. Methods are used to reduce the current consumption of the hall sensors to increase battery life when running from the backup power source.

Frequently Asked Questions (FAQ)

  • Q: What is the difference between a 1N4148 and a 1N914?

    A: For a number of devices digikey (notably Fairchild) lists the leakage current for the 1N4148 as 5 µA, the same as the 1N914. But for others (e.g. NXP) the leakage current is only 25 nA. Which would make the 1N4148 a better alternative to the 1N914. more

  • Q: What are 1N4148 diode applications?

    A: The switching diode is the most basic function of almost every electronic application. Switching diodes are also used in high-speed rectifying applications, such as in radiofrequency receivers. Applications also include high-speed switching, general-purpose switching and reverse polarity protection in the consumer, automotive, and telecommunication industry. more

  • Q: Is there a 1N4148 zener diode?

    A: The 1N4148 is a standard silicon switching diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost.The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns. more

  • Q: What are some 1N4148 diode equivalents?

    A: You can replace 1N4148 with 1N4448WS, 1N4448W, 1N4448, 1N4148WS, 1N4148W more

  • Q: Where can I find 1N4148 switching diode specifications?

    A: The most widely used of all the glass encapsulated signal diodes is the very common 1N4148 and its equivalent 1N914 signal diode.Small signal and switching diodes have much lower power and current ratings, around 150mA, 500mW maximum compared to rectifier diodes, but they can function better in high frequency applications or in clipping and switching applications that deal with short-duration pulse waveforms. more

  • Q: What is the forward voltage drop on 1N4148?

    A: For ultra-low power use and the low voltage levels involved, you need to be careful about the type of diode used. A regular 1N4148 silicon diode has a forward drop of about 0.65V, quite a bit when supplies are 2..3V! more

  • Q: What is the difference between a 1N4148 and a 1N4001?

    A: Both diodes work the same way by allowing current to flow in one direction. The differences have to do with power and frequency characteristics. They are made from a p-n junction and are two lead devices. more

  • Q: Where can I find a 1N4148 in sod323 package?
