MAX698/MAX699
Low-Cost, Power-On Reset
and Watchdog Controllers
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 condi-
tions. 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 microproces-
sor activity. The RESET output goes low if the watchdog

input (WDI) is not toggled within 1 second. The watch-
dog 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 speci-
fied 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 ).
