EM Microelectronic H6061
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. The device is specially suited to telecommunications applications where 3 V working is expected, for functions such as supply voltage and microprocessor monitoring.| Part No. | H6061 |

DESCRIPTION
The reset outputs are self recovering after a watchdog timeout, enabling the circuit to work with standalone systems without any external pushswitch or control signal to restart after a watchdog timeout. The circuit provides a reset signal of both polarities. The state of the outputs is defined down to 1.6 V. An internal debouncer ensures power-up performance for fast-rise supply lines.FEATURES
● 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-down
● Reset outputs of both polarities
● Open drain outputs
● SO8 package
