MAX823/4/5  
Voltage Supervisor with Watchdog Timer  
and Manual Reset  
General Description  
Features  
The MAX823/4/5 voltage supervisory circuits combine low-  
current, manual reset input, watchdog timer, active-high  
and active-low push-pull outputs. The reset outputs are  
asserted and held when the supply voltage falls below the  
factory-programmed threshold voltage, when the /MR pin  
is pulled low, or if the watchdog times out. Reset is  
asserted for the reset timeout delay after the supply  
voltage increases above the rising threshold voltage or  
when manual reset input is asserted high.  
Precision 1.665V to 4.625V power supply monitor  
±0.5% threshold accuracy at TA = +25°C  
±1.5% threshold accuracy from TA = –40°C to +125°C  
3.8µA supply current (S,R,T,W,Y,Z options)  
4.8µA supply current (L,M options)  
Manual reset input (MAX823/5)  
140ms (min.) reset timeout period  
1.6s (typ.) watchdog timeout period  
The MAX823/4/5 features an integrated pull-up resistor on  
the /MR pin. An active-low push-pull reset output (/RESET)  
and an active-high reset output (RESET) provide flexibility  
when interfacing with various microcontrollers, PMICs, or  
load switches. The watchdog input can be left  
unconnected for applications that do not require watchdog  
monitoring.  
Active-high and active-low push-pull outputs  
Guaranteed reset output valid to VCC = 1V  
• −40°C to +125°C junction temperature range  
5-pin SOT23 and SC70 packages  
8x lower watchdog input current than competition  
Applications  
The MAX823/4/5 consumes a quiescent current of only  
3.8µA and is offered in standard SOT23-5 and SC70-5  
packages. It is rated for the –40°C to +125°C temperature  
range.
