returns and exceeds V
TRIP2
.This voltage sense cir-
cuitry monitors the power supply connected to V2MON
pin. If V
CC
= 0, V2MON can still be monitored.
For the X40034 and X40035, the V2FAIL signal
remains active until V
CC
drops below 1V and remains
active until V2MON returns and exceeds V
TRIP2
.This
sense circuitry is powered by V
CC
. If V
CC
= 0, V2MON
cannot be monitored.
Low Voltage V3 Monitoring
The X40030, X40031, X40034, X40035 also monitors
a third voltage level and asserts V3FAIL if the voltage
falls below a preset minimum V
TRIP3
. The V3FAIL sig-
nal is either ORed with RESET to prevent the micro-
processor from operating in a power fail or brownout
condition or used to interrupt the microprocessor with
notification of an impending power failure. The V3FAIL
signal remains active until the V3MON drops below 1V
(V3MON falling). It also remains active until V3MON
returns and exceeds V
TRIP3
.
This voltage sense circuitry monitors the power supply
connected to V3MON pin. If V
CC
= 0, V3MON can still
be monitored.
