5% reset: Reset does not assert until the regulator out-
put voltage is at least -5% out of tolerance and always
asserts before the regulator output voltage is -10% out of
tolerance.
10% reset: Reset does not assert until the regulator
output voltage is at least -10% out of tolerance and
always asserts before the regulator output voltage is
-15% out of tolerance.
A µP’s reset input starts the µP in a known state. The
MAX6329/MAX6349 µP supervisory circuits assert a
reset during power-up, power-down, and brownout
conditions. Reset is guaranteed to be logic high or low
depending on the device chosen (see Selector Guide).

MAX6329 provides a digitally controlled active-low
shutdown function. In shutdown mode the pass transis-
tor, control circuit, reference, and all biases turn off,
reducing the supply current to below 1µA. Connect
SHDN to IN for normal operation.
Many µP-based products require manual reset capabil-
ity, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. For the MAX6349, a
