DATASHEET Ɩ H6060
Self Recovering Watchdog
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 P 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 (VIN)
and the regulated voltage (VDD) monitoring simultaneously.
The H6060 initializes the power-on reset after VIN reaches
VSH (see table 4) and VDD rises above 3.V. If VIN drops
below VSL (see table 4), the H6060 gives an advanced
warning signal for register saving and if the voltage drops
further below VRL (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.
Typical Operating Configuration
Features
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 (VIN) with 3 standard or
programmable trigger voltages for: power-on reset
initialization, advanced power-fail warning ( SAVE ),
reset at power-down ( RES )
Regulated DC monitoring (VDD): power-on reset
initialization enabled only if VDD 3.5 V
Internal voltage reference
Works down to 1.6 V supply voltage
Push-pull or Open drain outputs
Low current consumption
