View Datasheet Manufacturer Site View Pricing & Stock

The MAX698/MAX699 monitor the +5V supply in microprocessor (µP) and digital systems. They supply a active-low RESET pulse of at least 140ms duration on power-up, power-down, and during low-voltage brownout conditions. Circuit reliability is increased at reduced cost by eliminating all external components and adjustments. The MAX699 includes all features of the MAX698, but also provides a watchdog input to monitor microprocessor activity. The active-low RESET output goes low if the watchdog input (WDI) is not toggled within 1 second. The watchdog feature can be disabled by leaving WDI open. Both parts are supplied in 8-lead PDIP and 16-lead 0.3in wide small outline (SO) packages and are specified from 0°C to +70°C for C grade devices and -40°C to +85°C for E devices. The SO versions, with more pins than the 8-lead PDIP, have additional outputs not available in DIP packages. These are RESET (without inversion) and watchdog output (active-low WDO).
