DESCRIPTION The X80140 is a voltage supervisor/sequencer with four built in voltage monitors. This allows the designer to monitor up to four voltages and sequence up to five events. Low voltage detection circuitry protects the system from power supply failure or "brown out" conditions, resetting the system and resequencing the voltages when any of the monitored inputs fall below the minimum threshold level. The RESET pin is active until all monitored voltages reach proper operating levels and stabilize for a selectable period of time. Five common low voltage combinations are available, however, Xicor's unique circuits allow the any voltage monitor threshold to be reprogrammed for special needs or for applications requiring higher precision. A manual reset input provides debounce circuitry for minimum reset component count. Activating the manual reset both controls the RESET output and resequences the supplies through control of the ViGDO pins. The X80140 has 2kb of EEPROM for system configuration, manufacturing or maintenance information. This memory is protected to prevent inadvertent changes to the contents.
