MAX698-MAX699
Low-Cost Power On Reset IC
General Description
The MAX698/MAX699 monitor the +5V supply in micro-processor (μP) and digital systems. They supply a
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 eliminat-ing all external components and adjustments.
The MAX699 includes all features of the MAX698, but also provides a watchdog input to monitor microproces-sor activity. The 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 (WDO).
Applications●Computers●Controllers●Intelligent Instruments●Critical μP Power Monitoring
Features●Precision Voltage Monitor●Power-OK/Reset Time Delay●Watchdog Timer●Minimum Component Count
*Devices are available in both leaded and lead(Pb)-free pack-
aging. Specify lead free by adding the + symbol at the end of
the part number when ordering.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
