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 V1MON is detected as over-voltage or

under-voltage, or the voltage at V2MON 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.

V4OUT

V4OUT is an open-drain output triggered by V4MON wth

minimum propogation delay and the programmable delay

does not apply. V4OUT can be used as a PWM control over an

external device or used as a monitoring signal. Most

applications using V4OUT require disabling V4MON triggered

reset with an I2C command.
