Voltage Supervisor/Sequencer
Quad Programmable Time Delay with
Local/Remote Voltage Monitors
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, Intersil’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.
