Applications Information
Microprocessor Reset
The /RESET pin is asserted whenever V
reset threshold voltage. The reset pin remains asserted for a
period of 1100ms after V
old voltage. The reset function ensures the microprocessor
is properly reset and powers up into a known condition after
a power failure. /RESET will remain valid with V
as 1V.
V
The MIC8115 is relatively immune to the negative-going V
glitches below the reset threshold. Typically, a negative-going
transient 125mV below the reset threshold with a duration of
20µs or less will not cause a reset.

/RESET Valid at Low Voltage
A resistor can be added from the /RESET pin-to-the ground
to ensure the /RESET output remains low with V
0V. A 100kΩ resistor connected from /RESET-to-ground is
recommended. The resistor should be large enough not to
load the /RESET output and small enough to pull-down any
stray leakage currents.
