Single-/Dual-/Triple-Voltage µP Supervisory  
Circuits with Independent Watchdog Output  
General Description  
Features  
♦ V 1 (Primary Supply) Reset Threshold Voltages  
The MAX6730A–MAX6735A single-/dual-/triple-voltage  
microprocessor (µP) supervisors feature a watchdog  
timer and manual reset capability. The MAX6730A–  
MAX6735A offer factory-set reset thresholds for moni-  
toring voltages from +0.9V to +5V and an adjustable  
reset input for monitoring voltages down to +0.63V. The  
combination of these features significantly improves  
system reliability and accuracy when compared to sep-  
arate ICs or discrete components.  
CC  
from +1.575V to +4.63V  
♦ V 2 (Secondary Supply) Reset Threshold  
CC  
Voltages from +0.79V to +3.08V  
♦ Adjustable RSTIN Threshold for Monitoring Voltages  
Down to +0.63V (MAX6734A/MAX6735A Only)  
♦ Six Reset Timeout Options  
♦ Watchdog Timer with Independent Watchdog Output  
35s (min) Initial Watchdog Startup Period  
The active-low reset output asserts and remains asserted  
for the reset timeout period after all the monitored volt-  
ages exceed their respective thresholds. Multiple factory-  
set reset threshold combinations reduce the number of  
external components required. The MAX6730A/  
MAX6731A monitor a single fixed voltage, the MAX6732A/  
MAX6733A monitor two fixed voltages, and the  
MAX6734A/MAX6735A monitor two fixed voltages and one  
adjustable voltage. All devices are offered with six mini-  
mum reset timeout periods ranging from 1.1ms to 1120ms.  
1.12s (min) Normal Watchdog Timeout Period  
♦ Manual Reset Input (MAX6730A/MAX6731A/  
MAX6734A/MAX6735A)  
♦ Guaranteed Reset Valid down to  
V
1 or V 2 = +0.8V

♦ Push-Pull RESET or Open-Drain RESET Output  
♦ Immune to Short V Transients  
CC  
The MAX6730A–MAX6735A feature a watchdog timer  
with an independent watchdog output. The watchdog  
timer prevents system lockup during code execution  
errors. A watchdog startup delay of 54s after reset  
asserts allows system initialization during power-up.  
The watchdog operates in normal mode with a 1.68s  
delay after initialization. The MAX6730A/MAX6732A/  
MAX6734A provide an active-low, open-drain watch-  
dog output. The MAX6731A/MAX6733A/MAX6735A  
provide an active-low, push-pull watchdog output.  
♦ Low Supply Current: 14µA (typ) at +3.6V  
♦ Small 6-Pin and 8-Pin SOT23 Packages

Other features include a manual reset input (MAX6730A/  
MAX6731A/MAX6734A/MAX6735A) and push-pull reset  
output (MAX6731A/MAX6733A/MAX6735A) or open-  
drain reset output (MAX6730A/MAX6732A/MAX6734A).  
The MAX6730A–MAX6733A are offered in a tiny 6-pin  
SOT23 package. The MAX6734A/MAX6735A are offered  
in an 8-pin, space-saving SOT23 package. All devices  
are fully specified over the extended -40°C to +125°C  
temperature range.

ber. For example, the MAX6732AUTLTD3-T provides a V

threshold of +4.625V, a V 2 threshold of +3.075V, and a  
CC  
210ms reset timeout period. Sample stock is generally held on  
standard versions only (see the Standard Versions table).  
Standard versions have an order increment requirement of 2500  
pieces. Nonstandard versions have an order increment require-  
ment of 10,000 pieces. Contact factory for availability.  
Devices are available in both leaded and lead-free packaging.  
Specify lead-free by replacing “T” with “+T” when ordering.
