General Description
The MAX6736–MAX6745 are low-power dual-/triple-
voltage microprocessor (P) 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 6A makes these
devices ideal for portable equipment.
The MAX6736/MAX6737 are dual fixed-voltage P
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 P supervisors with two
fixed and one user-adjustable reset threshold inputs.
The MAX6741/MAX6744 are dual-voltage P supervi-
sors with a power-OK (POK) output ideal for power-
supply sequencing. The MAX6742/MAX6745 monitor
the primary VCC supply and have an independent
power-fail comparator.
The MAX6736–MAX6745 monitor I/O supply voltages
(VCC1) from 1.8V to 5.0V and core supply voltages
(VCC2) from 0.9V to 3.3V with factory-trimmed reset
threshold voltage options (Table 1). An external
adjustable RSTIN input option allows monitoring volt-
ages down to 0.5V.
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.

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-
age supervisor VTH1 = 4.625V, VTH2 = 3.075V, and a 150ms
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.
