The MAX16025–MAX16030 are low-voltage, accurate,
dual-/triple-/quad-voltage microprocessor (µP) supervi-
sors in a small TQFN package. These devices provide
supervisory and sequencing functions for complex mul-
tivoltage systems. The MAX16025/MAX16026 monitor
two voltages, the MAX16027/MAX16028 monitor three
voltages, and the MAX16029/MAX16030 monitor four
voltages.
The MAX16025–MAX16030 offer independent outputs
and enable functions for each monitored voltage. This
configuration allows the device to operate as four sepa-
rate supervisory circuits or be daisy-chained together to
allow controlled sequencing of power supplies during

power-up initialization. When all of the monitored volt-
ages exceed their respective thresholds, an indepen-
dent reset output deasserts to allow the system
processor to operate.
These devices offer enormous flexibility as there are
nine threshold options that are selected through two
threshold-select logic inputs. Each monitor circuit also
offers an independent enable input to allow both digital
and analog control of each monitor output. A tolerance
select input allows these devices to be used in systems
requiring 5% or 10% power-supply tolerances. In addi-
tion, the time delays and reset timeout can be adjusted
using small capacitors. There is also a fixed 140ms
minimum reset timeout feature.
