H6061

The H6061 is a combined initialiser, watchdog and voltage monitor. The H6061 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. The reset outputs are self recovering after a watchdog timeout, enabling the circuit to work with standalone systems without any external push-switch 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 perfomance for fast-rise supply lines.
