Ultra-Low-Power Voltage Detectors and  
µP Supervisory Circuits  
General Description  
Features  
The MAX6461–MAX6466 family of ultra-low-power voltage  
detectors and µP reset supervisory circuits monitors bat-  
tery, power-supply, and system voltages. Each circuit  
includes a precision bandgap reference, a comparator,  
internally trimmed resistor networks that set specified trip  
thresholds, and an internal 5% threshold hysteresis circuit  
(see the Functional Diagram). Output is asserted when  
o Ultra-Low 1.0µA Supply Current  
o Preset Thresholds from +1.6V to +5.5V in 100mV  
Increments  
o Internal 5% Threshold Hysteresis  
o ±±.5% Threshold Accuracy ꢀOer Temperature  
o Internal Timeout Period ꢀption (150ms min)  
o Immune to Short Voltage Transients  
o No External Components

devices provide excellent circuit reliability and low cost  
by eliminating external components and adjustments  
when monitoring nominal system voltages from +1.6V to  
+5.5V. The MAX6461/MAX6462/MAX6463 are voltage  
detectors with a propagation delay of 17µs.  
o AOailable in Three ꢀutput ꢀptions: Push-Pull  
(ActiOe Low/ActiOe High) and ꢀpen Drain (ActiOe  
Low)  
The MAX6464/MAX6465/MAX6466 are µP supervisory  
circuits with a minimum reset timeout period of 150ms. All  
devices are available with thresholds from +1.6V to +5.5V  
in 100mV increments.  
o Fully Specified from -40°C to +1±5°C  
o Small SC70 and SꢀT±3 Packages  
Ordering Information  
The family is available with three output stage options:  
push-pull with active-low output, push-pull with active-  
high output, and open drain with active-low output. These  
devices are available in SC70 and SOT23 packages  
specified over the -40°C to +125°C temperature range.

Applications  
Precision Battery Monitoring  
Load Switching/Power Sequencing  
The MAX6461–MAX6466 are available in factory-set thresholds  
from 1.6V to 5.5V in approximately 100mV increments. Choose  
the desired voltage threshold suffix from Table 1 and insert it in  
the blank spaces in the part number. There are 30 standard ver-  
sions with a required order increment of 2500 pieces. Sample  
stock generally is held on the standard versions only (Table 2).  
Nonstandard versions require a 10k-piece order increment.  
Contact factory for availability. All devices available in tape-and-  
reel only.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional  
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to  
absolute maximum rating conditions for extended periods may affect device reliability.

When V  
falls below 1V, the MAX6461/MAX6464 out-

put sinking capability is reduced. Therefore, high-  
impedance CMOS logic inputs connected to OUT can  
drift to undetermined voltages. This presents no prob-

where OUT must be valid down to ground, add a pull-  
down resistor to ground so any stray leakage currents  
flow to ground, holding OUT low. Select a resistor large  
enough not to load OUT and small enough to pull OUT  
to ground. For most applications, 100kΩ does not load  
OUT and pulls OUT to ground.  
The MAX6463 and MAX6466’s active-low, open-drain out-

voltage than V , as shown in Figure 1. This output struc-

pullup resistor from OUT to any supply from 0 to 6V.  
Select a resistor value large enough to allow a valid logic  
low (see the Electrical Characteristics) and small enough  
to register a logic high while supplying all input current  
and leakage paths connected to the OUT pin.

Package Information  
For the latest package outline information, go to  
www.maxim-ic.com/packages.)  
The MAX6461–MAX6466 are available in factory-set thresholds  
from 1.6V to 5.5V in approximately 100mV increments. Choose  
the desired voltage threshold suffix from Table 1 and insert it in  
the blank spaces in the part number. There are 30 standard ver-  
sions with a required order increment of 2500 pieces. Sample  
stock generally is held on the standard versions only (Table 2).  
Nonstandard versions require a 10k-piece order increment.  
Contact factory for availability. All devices available in tape-and-  
reel only.  
Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are
