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 (P) 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 10A
current source. MR is designed to reject fast, falling
transients (typically 100ns pulses) and must be held low
for a minimum of 1s to assert RESET. After MR transi-
tions from low to high, RESET remains asserted for the
duration of its timeout period.
