Superior Upgrade for DS1232
The LTC
®
1232 provides power supply monitoring,
watchdog timing and external reset for microprocessor
systems. A precise internal voltage reference and
comparator circuit monitor the power supply line. When
an out-of-tolerance condition occurs, the reset outputs
are forced to active states. The RST output is guaranteed
to remain logic low even with V
CC
as low as 1V.
The LTC1232 has an internal watchdog timer which forces
the reset outputs to active states when the Strobe input is
not forced low prior to a preset time-out period. The
watchdog timing can be set to operate on time-out periods
of typically 150ms, 600ms or 1.2 seconds.
The LTC1232 performs push-button reset control.
The LTC1232 debounces the push-button input
and guarantees an active reset pulse width of 250ms
minimum.
