MAX6340/MAX6421–  
Low-Power, SC70/SOT µP Reset Circuits  
MAX6426  
with Capacitor-Adjustable Reset Timeout Delay  
General Description  
The MAX6340/MAX6421–MAX6426 low-power micropro-  
cessor supervisor circuits monitor system voltages from  
1.6V to 5V. These devices perform a single function: they  
assert a reset signal whenever the V  
falls below its reset threshold. The reset output remains  
asserted for the reset timeout period after V rises  
above the reset threshold. The reset timeout is externally  
set by a capacitor to provide more flexibility.

The MAX6421/MAX6424 have an active-low, push-  
pull reset output. The MAX6422 has an active-high, push-  
pull reset output and the MAX6340/MAX6423/ MAX6425/  
MAX6426 have an active-low, open-drain reset output.  
The MAX6421/MAX6422/MAX6423 are offered in 4-pin  
SC70 or SOT143 packages. The MAX6340/MAX6424/  
MAX6425/MAX6426 are available in 5-pin SOT23-5  
packages.
