Application Information
Output
The MIC845N output is an open-drain MOSFET, so
most applications will require a pull-up resistor. It is
recommended that the value of this resistor not
exceed 470k, otherwise PCB leakages may begin
to dominate and give a false output indication.
The output of “N” type devices may be pulled up as
high as 6V regardless of the IC’s supply voltage,
without damage to the IC.
The “H” and “L” versions of MIC845 have push-pull
output stages, no pull-up resistors are required. The
maximum output voltage of the “H” and “L” versions
is VDD.
Input
MIC845 has been designed to present an almost
infinite input resistance at its INP pin making it ideal
for monitoring lithium coin cell and back-up batteries.
In applications where the ‘battery low’ voltage is
2.55V, MIC845’s INP pin may be tied directly to the
cell’s positive terminal without any additional
circuitry.
MIC845’s input may be subjected to voltages as high
as 6V, steady-state, without any adverse effects,
regardless of the IC’s supply voltage. This applies
even if the supply voltage is zero. This permits a
situation wherein the IC’s supply is turned off, but an
input voltage is still present. Under such conditions,
there will be no conduction from INP to VDD or any
circuitry internal to MIC845.
Input Transients
MIC845 is inherently immune to very short
negative-going “glitches.” Very brief transients may
exceed the VINP threshold without tripping the output.
As shown in the figure below, the narrower the
transient, the deeper the threshold overdrive that will
be ignored by the MIC845. The graph represents the
typical allowable transient duration for a given
amount of threshold overdrive that will not generate
an output.
