Superior Upgrade for MAX699
The LTC699 provides power supply monitoring for
microprocessor-based systems. The features include mi-
croprocessor reset and watchdog timing. Precise internal
voltage reference and comparator circuit monitor the
power supply line. When an out-of-tolerance condition
occurs, the RESET output is forced to active low. In
addition, the RESET output is guaranteed to remain logic
low even with V
CC
as low as 1V.
An internal watchdog timer is also available, which forces
the RESET output to active low when the watchdog input
is not toggled prior to the time-out period of 1.6 seconds.
The LTC699 is offered in DIP and surface mount packages.
