MAX6453–MAX6456
µP Supervisors with Separate V
CC
Reset and
Manual Reset Outputs
General Description
The MAX6453–MAX6456 are low-power, dual-voltage
µP supervisors featuring separate V
CC
reset and manu-
al reset outputs. The dual outputs support both soft-
system reset (interrupt) and hard-system reset (reboot)
functions. The reset output asserts when any of the
monitored voltages falls below its specified threshold
and remains asserted for the reset timeout (140ms min)
after all voltages exceed their respective reset thres-
holds. All devices are offered with nine factory-fixed
reset thresholds for monitoring primary system voltages
(V
CC
) from 1.8V to 5V and an adjustable reset input for
monitoring a secondary system voltage down to 0.63V.
Each device has a manual reset input, a V
CC
reset out-
put, and a manual reset output. The MAX6453/MAX6454
manual reset output asserts when the manual reset input
is low. It remains asserted for the manual reset timeout
period (140ms min) after the manual reset input transi-
tions high. The MAX6453/MAX6454 manual reset input
controls only the manual reset output and does not affect
the V
CC
reset output.
The manual reset input of the MAX6455/MAX6456 con-
trols both the manual reset and V
CC
reset outputs. When
the manual reset input is low for less than the extended
setup timeout period, only the manual reset output asserts
and remains asserted for the manual reset timeout period
(140ms min) after the manual reset input transitions high.
If the manual reset input is low for at least the extended
setup timeout period, the reset output also asserts and
remains asserted for the reset timeout period (140ms
min) after the manual reset input transitions high. This
enhanced feature allows the implementation of a soft/
hard-system reset combination.
The MAX6453/MAX6455 have active-low, push-pull
reset and manual reset outputs, and the MAX6454/
MAX6456 have active-low, open-drain reset and manu-
al reset outputs. All devices are available in small
SOT23-6 packages and are fully specified over the
extended temperature range (-40°C to +85°C).

Note: The first “_ _” is a placeholder for the threshold voltage
level of the devices. A desired threshold level is set by the part
number suffix found in Table 1. The third “_” is a placeholder for
the manual reset setup period of the devices. A desired setup
period is set by the letter suffix found in Table 2. All devices are
available in tape-and-reel only. There is a 2500-piece minimum
order increment for standard versions (Table 2). Sample stock
is typically held on standard versions only. Nonstandard ver-
sions require a minimum order increment of 10,000 pieces.
Contact factory for availability.
Devices are available in both leaded and lead(Pb)-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
