H6061 - 3V Self Recovering Watchdog

The H6061 is a combined initialiser, watchdog and voltage monitor.

The circuit is a low voltage low power monolithic CMOS device combining a series of voltage comparators and a programmable timer on the same chip.

•  Watchdog fully operational from 2.7 to 5.25 V  Regulated DC voltage monitor, internal voltage reference  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 from 3 ms to 3 mins if required  Works down to 1.6 V supply voltage  Low voltage alarm prior to reset on power-.
