Microprocessor Reset
The RESET pin is asserted whenever VCC falls below
the reset threshold voltage or if MR (manual reset) is
forced low. The reset pin remains asserted for a period
of at least 790ms after VCC has risen above the reset
threshold voltage or MR has returned high. The reset
function ensures the microprocessor is properly reset
and powers up into a known condition after a power fail-
ure. RESET will remain valid with VCCas low as 1.4V.
VCCTransients
The MIC8114 is relatively immune to negative-going
VCC glitches below the reset threshold. Typically, a
negative-going transient 125mV below the reset
threshold with a duration of 25
μ
s or less will not cause
an unwanted reset.
RESET Valid to 0V
A resistor can be added from the RESET pin to ground
to ensure the RESET output remains low with VCC
down to 0V. A 100K
resistor connected from RESET
to ground is recommended. The size of the resistor
should be large enough to not load the RESET output
and small enough to pull-down any stray leakage
currents.
