MIC841/2 Applications Information Output The MIC841N and MIC842N outputs are an open-drain MOSFET, so most applications will require a pull-up resistor. The value of the resistor should not be too large or leakage effects may dominate. 470kΩ is the maximum ...

MIC841/2 Input Transients The MIC841/2 is inherently immune to very short negative- going “glitches.” Very brief transients may exceed the V threshold without tripping the output. As shown in Figure 3, the narrower the transient, the deeper the threshold overdrive ...
