for the Specific /V Trim Version
The MAX6381–MAX6390 microprocessor (μP) supervi-
sory 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 asserted
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 increments.
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.
