Low-Power Dual-/Triple-Voltage SC70 µP  
Supervisory Circuits  
General Description  
Features  
The MAX6736–MAX6745 are low-power dual-/triple-  
voltage microprocessor (µP) supervisors. These  
devices assert a reset if any monitored supply falls  
below its factory-trimmed or adjustable threshold and  
maintain reset for a minimum timeout period after all  
supplies rise above their thresholds. The integrated  
dual/triple supervisory circuits significantly reduce size  
and power compared to separate ICs or discrete com-  
ponents. The low supply current of 6µA makes these  
devices ideal for portable equipment.  
♦ Dual-/Triple-Supply Reset Voltage Monitors  
♦ Precision Factory-Set Reset Thresholds for  
Monitoring from 0.9V to 5.0V  
♦ Adjustable Reset Input Down to 0.488V  
♦ 150ms and 1200ms (min) Reset Timeout Period  
Options  
♦ V 1 Power-OK Output for Power-Supply  
CC  
Sequencing Applications (MAX6741/MAX6744)  
♦ Power-Fail Input/Power-Fail Output  
The MAX6736/MAX6737 are dual fixed-voltage µP  
supervisors with a manual reset input. The MAX6738/  
MAX6739 have one fixed and one adjustable reset  
threshold and a manual reset input. The MAX6740/  
MAX6743 are triple-voltage µP supervisors with two  
fixed and one user-adjustable reset threshold inputs.  
The MAX6741/MAX6744 are dual-voltage µP supervi-  
sors with a power-OK (POK) output ideal for power-  
supply sequencing. The MAX6742/MAX6745 monitor  
(MAX6742/MAX6745)  
♦ 6µA Supply Current  
♦ Tiny SC70 Package

Note: The first “_ _” or “_” are placeholders for the threshold  
voltage levels of the devices. Desired threshold levels are set  
by the part number suffix found in Tables 1 and 2. The “_” after  
the D is a placeholder for the reset timeout period suffix found  
in Table 3. For example, the MAX6736XKLTD3-T is a dual-volt-

minimum reset timeout period. All devices are available in  
tape-and-reel only. There is a 2500-piece minimum order  
increment for standard versions (see Table 1). Sample stock is  
typically held on standard versions only. Nonstandard versions  
require a minimum order increment of 10,000 pieces. Contact  
factory for availability.  
A variety of push-pull or open-drain reset outputs along  
with manual reset input and power-fail input/output fea-  
tures are available (see the Selector Guide). The  
MAX6736–MAX6745 are offered in a space-saving 5-pin  
SC70 package and operate over the -40°C to +85°C  
temperature range.  
Devices are available in both leaded and lead-free packaging.  
Specify lead-free by replacing “-T” with “+T” when ordering.
