Ultra-Low-Voltage SC70 Voltage Detectors  
and µP Reset Circuits  
General Description  
Features  
ꢀ Factory-Set Reset Threshold Voltages for  
The MAX6832–MAX6840 are microprocessor (µP)  
supervisory circuits used to monitor low-voltage power  
supplies in µP and digital systems. They provide excel-  
lent circuit reliability and low cost by eliminating exter-  
nal components and adjustments when used with  
+1.2V to +1.8V powered circuits.

above the reset threshold or when manual reset is  
deasserted. Five different timeout periods are available:  
70µs (voltage detector), 1.5ms, 30ms, 210ms, and 1.68s.  
Reset thresholds suitable for operation with a variety of  
supply voltages are available.

The MAX6832/MAX6835/MAX6838 have a push-pull  
active-low reset output (RESET). The MAX6833/  
MAX6836/MAX6839 have a push-pull active-high reset  
output (RESET) and the MAX6834/MAX6837/MAX6840  
have an open-drain active-low reset output (RESET). The

Ordering Information  
Low supply current of 7.5µA makes the MAX6832–  
MAX6840 ideal for use in portable equipment. These  
devices are available in 3- and 4-pin SC70 packages.
