the IN inputs only at power-up. Use the voltage-divider
circuit of Figure 1 and Equation 1 to set the threshold
for the user-adjustable inputs as described in the
Voltage-Detector Inputs (IN_)
section.
Manual Reset (
MR
)
Many microprocessor-based (μP) products require
manual reset capability to allow an operator or external
logic circuitry to initiate a reset. The manual reset input
(
MR
) can be connected directly to a switch without an
external pullup resistor or debouncing network.
MR
is
internally pulled up to DBP. Leave unconnected if not
used.
MR
is internally pulled up to DBP through a 10μA
current source.
MR
is designed to reject fast, falling
transients (typically 100ns pulses) and must be held low
for a minimum of 1μs to assert
RESET
. After
MR
transi-
tions from low to high,
RESET
remains asserted for the
duration of its timeout period.
