Fault Detection with Shutdown Warning
An early shutdown warning is available for the system
processor to identify the source of failure and take
appropriate action before shuting down the external devices.
Whenever the voltage at V
1MON
is detected as over-voltage or
under-voltage, or the voltage at V
2MON
falls below the
threshold,
SHDNWARN
outputs a logic 0. If the processor sees
a logic-low on this pin, the processor may issue an I2C read
command to identify the cause of failure reported in the Fault
Detect/Status Register. The processor may store the
information in the external EEPROM as a record of failure
history.
V
4OUT
V
4OUT
is an open-drain output triggered by V
4MON
wth
minimum propogation delay and the programmable delay
does not apply. V
4OUT
can be used as a PWM control over an
external device or used as a monitoring signal. Most
applications using V
4OUT
require disabling V
4MON
triggered
reset with an I2C command.
