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 combi-

nations 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 con-

trols the RESET output and resequences the supplies through

control of the ViGDO pins.

The X80140 has 2kb of EEPROM for system conﬁguration, man-

ufacturing or maintenance information. This memory is protected

to prevent inadvertent changes to the contents.
