Features
Description
The H6060 is a monolithic low-power CMOS device
combining a programmable timer and a series of voltage
comparators on the same chip. The device is specially
suited for watchdog functions such as microprocessor
and supply voltage monitoring. If the µP system
malfunctions, the watchdog will recover it by issuing
repeated active reset signals. The voltage monitoring
part provides double security by combining both the
unregulated voltage (V
monitoring simultaneously. The H6060 initializes the
power-on reset after V
V
the H6060 gives an advanced warning signal for
register saving and if the voltage drops further below V
(see table 4), RES and RES go active. The H6060
functions at any supply voltage down to 1.6 V and is
therefore particularly suited for start-up and shut-down
control of microprocessor systems.
Applications
DD
Self recovering watchdog function: reset goes active
after the 1st timeout period, reset goes inactive
again after the 2nd timeout period, repeated active
reset signal until the system recovers
Standard timeout period and power-on reset time
(100 ms), externally programmable if required
Unregulated DC monitoring (V
programmable trigger voltages for: power-on reset
initialization, advanced power-fail warning (SAVE),
reset at power-down (RES)
Regulated DC monitoring (V
initialization enabled only if V
Internal voltage reference
Works down to 1.6 V supply voltage
