Low-Cost, Power-On Reset And Watchdog Controllers

The MAX698 MAX699 monitor the +5V supply in Microprocessor (P) 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 0C to +70C for C grade devices and -40C to +85C 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 4d9 inversion) and watchdog output (active-low WDO).
