Description
The H6006 is a monolithic low power CMOS device
combining a programmable digital timer and a series of
voltage comparators on the same chip. The device is
specially convenient for Watch-Dog functions such as
microprocessor and supply voltage monitoring. The
watchdog part is designed to be used in all applications
where it is important that after the occurrence of a
malfunction the microprocessor system is stopped to
avoid further damage. The timeout warning signal (TO)
can be used to try to reactivate the system before halting
it. The voltage monitoring part provides double security
by combining both unregulated voltage and regulated
voltage monitoring simultaneously. The H6006 initializes
the power-on reset after V
above 3.5 V. If V
advanced warning signal for register saving and if the
voltage drops further below V
H6006 functions at any supply voltage down to 1.5 V
and is therefore particularly suited for start-up and
shut-down control of microprocessor systems
Applications
Failsafe watchdog function: timeout warning after 1st
timeout period, reset after 2nd timeout period, reset
remains active to avoid further failures
Standard timeout period and power-on reset time
(10 ms), externally programmable if required
V
trigger voltages for: power-on reset initialization,
advanced power-fail warning (SAVE), reset at power-
down (RES)
