V INTH
OUT_ Output
The MAX16041/MAX16042/MAX16043 feature open-drain
outputs. An OUT_ goes low when its respective IN_ input

voltage drops below its specified threshold or when its
EN_ goes low (see Table 1). OUT_ goes high when EN_
is high and V IN_ is above its threshold after a time delay.
Open-drain outputs require an external pullup resistor to
any voltage from 0 to 28V.

Figure 3. Setting the Adjustable Input
The following equation is provided to help estimate the
value of the resistors based on the amount of acceptable
error:
e × V
I L
*When V CC falls below the UVLO, all outputs go low regardless
of the state of EN_ and V IN_ . The outputs are guaranteed to be
in the correct state for V CC down to 1.2V.

where e A is the fraction of the maximum acceptable
absolute resistive divider error attributable to the input
leakage current (use 0.01 for ±1%), V INTH is the voltage
at which the output (OUT_) should assert, and I L is the
worst-case IN_ leakage current (see the Electrical
Characteristics). Calculate R2 as follows:

Unused Inputs
Connect any unused IN_ and EN_ inputs to V CC .
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 thresholds, all EN_ are high, all
OUT_ are high, and MR is deasserted. All devices have
a push-pull, active-low reset output.
