3-Pin, Ultra-Low-Voltage, Low-Power  
μP Reset Circuits  
General Description  
Benefits and Features  
● Ultra-Low 0.7V Operating Supply Voltage  
The MAX6332/MAX6333/MAX6334 microprocessor (μP)  
supervisory circuits monitor the power supplies in 1.8V to  
3.3V μP and digital systems. They increase circuit reliability  
and reduce cost by eliminating external components and  
adjustments.  
● Low 3.3μA Supply Current  
● Precision Monitoring of 1.8V and 2.5V Power- Supply  
Voltages  
● Reset Thresholds Available from 1.6V to 2.5V,  
in Approximately 100mV Increments  
These devices perform a single function: they assert a  
reset signal whenever the V  
supply voltage declines  
CC  
● Fully Specified Over Temperature  
below a preset threshold, keeping it asserted for a preset  
timeout period after V has risen above the reset

● Three Power-On Reset Pulse Widths Available

threshold. The only difference among the three devices  
is their output. The MAX6333 (push/pull) and MAX6334  
(open-drain) have an active-low RESET output, while the  
MAX6332 (push/pull) has an active-high RESET output.  
The MAX6332/MAX6333 are guaranteed to be in the correct

between 1.6V and 2.5V, in approximately 100mV increments.  
There are 15 standard versions available (2,500 piece  
minimum-order quantity); contact the factory for availability  
of nonstandard versions (10,000 piece minimum-order  
quantity). For space-critical applications, the MAX6332/  
MAX6333/MAX6334 come packaged in a 3-pin SOT23.
