FUNCTION
Output 1. When the voltage at IN1 is below its threshold or EN1 goes low,
OUT1 goes low.
Active-Low Reset Output. RESET asserts low when any of the monitored
voltages (IN_) falls below its respective threshold, any EN_ goes low, or MR is

asserted. RESET remains asserted for the reset timeout period after all of the
monitored voltages exceed their respective threshold, all EN_ are high, all
OUT_ are high, and MR is deasserted.
Active-Low Manual Reset Input. Pull MR low to assert RESET low. RESET

Detailed Description
The MAX16041/MAX16042/MAX16043 are low-voltage,
accurate, dual-/triple-/quad-voltage microprocessor
(μP) supervisors in a small TQFN package. These
devices provide supervisory and sequencing functions
for complex multivoltage systems. The MAX16041 mon-
itors two voltages, the MAX16042 monitors three volt-
ages, and the MAX16043 monitors four voltages.
The MAX16041/MAX16042/MAX16043 offer indepen-
dent outputs and enable functions for each monitored
voltage. This configuration allows the device to operate as
four separate supervisory circuits or be daisy-chained
together to allow controlled sequencing of power supplies
during power-up initialization. When all of the monitored
voltages exceed their respective thresholds, an inde-
pendent 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.
