MAX6746–MAX6753  
μP Reset Circuits with Capacitor-Adjustable  
Reset/Watchdog Timeout Delay  
General Description  
Benefits and Features  
● Configurable Reset and Watchdog Options Enables  
Wide Variety of Applications  
The MAX6746–MAX6753 low-power microprocessor  
(μP) supervisory circuits monitor single/dual system  
supply voltages from 1.575V to 5V and provide maximum  
adjustability for reset and watchdog functions. These  
devices assert a reset signal whenever the V  
supply voltage or RESET IN falls below its reset threshold  
• Factory-Set Reset Threshold Options from 1.575V  
to 5V in ~100mV Increments  
• Adjustable Reset Threshold Options  
• Single/Dual Voltage Monitoring  
CC  
• Capacitor-Adjustable Reset Timeout  
• Capacitor-Adjustable Watchdog Timeout  
• Min/Max (Windowed) Watchdog Option  
• Manual-Reset Input Option  
or when manual reset is pulled low. The reset output  
remains asserted for the reset timeout period after V  
CC  
and RESET IN rise above the reset threshold. The reset  
function features immunity to power-supply transients.  
• Push-Pull or Open-Drain RESET Output Options  
The MAX6746–MAX6753 have ±2% factory-trimmed  
reset threshold voltages in approximately 100mV  
increments from 1.575V to 5.0V and/or adjustable reset  
threshold voltages using external resistors.  
● 3.7μA Supply Current Reduces System Power  
Consumption  
● Integrated Power Supply Protection Increases  
Robustness  
The reset and watchdog delays are adjustable with  
external capacitors. The MAX6746–MAX6751 contain  
a watchdog select input that extends the watchdog  
timeout period by 128x. The MAX6752/MAX6753 contain  
a window watchdog timer that looks for activity outside an  
expected window of operation.  
• Power-Supply Transient Immunity  
• Guaranteed RESET Valid for VCC ≥ 1V  
● 8-Pin SOT23 Packages Saves Board Space  
● AEC-Q100 Qualified. Refer to Ordering Information  
for Specific /V Trim Variants  
The MAX6746–MAX6753 are available with a push-pull  
or open-drain active-low RESET output. The MAX6746–  
MAX6753 are available in an 8-pin SOT23 package and  
are fully specified over the automotive temperature range  
(-40°C to +125°C).
