General Description

The MAX698/MAX699 monitor the +5V supply in microprocessor (µP) and digital systems. They supply a RESET pulse of at least 140ms duration on power-up, power-down, and during low-voltage brownout condi tions. Circuit reliability is increased at reduced cost by eliminating all external components and adjustments.
