SC70/µDFN, Single/Dual Low-Voltage,
Low-Power µP Reset Circuits
General Description
The MAX6381–MAX6390 microprocessor (µP) supervisory
circuits monitor power-supply voltages from +1.8V to
+5.0V while consuming only 3µA of supply current at
+1.8V. Whenever V
CC
falls below the factory-set reset
thresholds, the reset output asserts and remains assert-
ed for a minimum reset timeout period after V
CC
rises
above the reset threshold. Reset thresholds are available
from +1.58V to +4.63V, in approximately 100mV incre-
ments. Seven minimum reset timeout delays ranging
from 1ms to 1200ms are available.
The MAX6381/MAX6384/MAX6387 have a push-pull
active-low reset output. The MAX6382/MAX6385/
MAX6388 have a push-pull active-high reset output,
and the MAX6383/MAX6386/MAX6389/MAX6390
have an open-drain active-low reset output. The
MAX6384/MAX6385/MAX6386 also feature a
debounced manual reset input (with internal pullup
resistor). The MAX6387/MAX6388/MAX6389 have an
auxiliary input for monitoring a second voltage. The
MAX6390 offers a manual reset input with a longer V
CC
reset timeout period (1120ms or 1200ms) and a shorter
manual reset timeout (140ms or 150ms).
The MAX6381/MAX6382/MAX6383 are available in
3-pin SC70 and 6-pin µDFN packages and the
MAX6384–MAX6390 are available in 4-pin SC70 and
6-pin µDFN packages.
