X40420 monitor equivalent, dual voltage monitor.
* Dual voltage detection and reset assertion —Three standard reset threshold settings (4.6V/2.9V, 4.6V/2.6V, 2.9V/1.6V) —VTRIP2 Programmable down to 0.9V —Adjust low .
* Communications Equipment —Routers, Hubs, Switches —Disk arrays
* Industrial Systems —Process Control —Intellig.
The X40420/21 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary supervision, manual reset, and Block Lock™ protect serial EEPROM in one package. This combination lowers system cost, reduces board space require.
