Frequent questions
  • [FAQ] LM388x: What's the test condition for the question current?

    Sam
    Sam
    The test condition is that VCC=3.3 V and EN=3.3V. So it is an operating current when EN is high. For more LM388x FAQ click or type the tag in the search bar [FAQ] LM388x

  • [FAQ] LM388x: If the glitch occurs at EN pin, does it impact the FLAG output?

    Sam
    Sam
    EN pin has a glitch free operation. The first timer will start counting at a rising threshold of EN, but will always reset if the EN pin is de-asserted before the first output FLAG is released. Please refer section 7.3.1 of https://www.ti.com/lit/ds/symlink…
