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.
Reset Output
A P’s reset input starts the P in a known state. The
MAX6329/MAX6349 P 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).
RESET or RESET asserts when VOUT is below the reset
threshold and for at least 100ms (tRP) after VOUT rises
above the reset threshold. RESET or RESET also
asserts when MR is low (MAX6349).
Shutdown (MAX6329 Only)
SHDN allows for the regulator to shutdown thereby
reducing the total IIN consumption of the device. The
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 1A. Connect
SHDN to IN for normal operation.
Manual Reset Input (MAX6349 Only)
Many P-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
