Name
V2FAIL
Function
V2 Voltage Fail Output.
This open drain output goes LOW when V2MON is less than V
TRIP2
and goes
HIGH when V2MON exceeds V
TRIP2
. There is no power-up reset delay circuitry on this pin.
V2 Voltage Monitor Input.
When the V2MON input is less than the V
TRIP2
voltage, V2FAIL goes LOW.
This input can monitor an unregulated power supply with an external resistor divider or can monitor a
second power supply with no external components. Connect V2MON to V
SS
or
V
CC
when not used. The
V2MON comparator is supplied by V2MON (X40430, X40431) or by the V
CC
input (X40434, X40435).
LOWLINE
Early Low V
CC
Detect.
This CMOS output signal goes LOW when
V
CC
< V
TRIP1
and goes high when
V
CC
> V
TRIP1
.
NC
No connect.
