INTERRUPT Register [A2, A1, A0] = [000] (continued)
BIT
NAME
DESCRIPTION
DO Driver Fault Interrupt
1: This bit is set when a fault occurs on the DO driver (over current or over heating).
5
DoFaultInt
Once set, this bit is not cleared until the register is read. The current status of the
thermal shutdown condition can be read in the Status register.
0: No fault on the DO driver.
C/Q Driver Fault Interrupt
1: This bit is set when a fault occurs on the C/Q driver (over current or over heating).
4
CQ_FaultInt
Once set, this bit is not cleared until the register is read. The current status of the
thermal shutdown condition can be read in the Status register.
0: No fault on the C/Q driver.
V24 Low Voltage Warning Interrupt
1: This bit is set when V₂₄ falls below the IO-Link low-voltage warning threshold fault
3
V24WInt
(V₂₄ < V_24W). Once set, this bit is not cleared until the register is read. The current
status of the thermal shutdown condition can be read in the Status register.
0: V₂₄ is greater than the low-voltage warning threshold.
V24 Supply Undervoltage Interrupt
1: This bit is set when V₂₄ falls below the UVLO threshold (V₂₄ < V_24UVLO). Once
2
UV24Int
set, this bit is not cleared until the register is read. The current status of the thermal
shutdown condition can be read in the Status register.
0: V₂₄ is greater than the UVLO threshold.
1

This bit is not used.
Overtemperature Warning Interrupt
1: This bit is set when the die temperature exceeds the warning threshold (T_J > T_WRN).
0
TempWInt
Once set, this bit is not cleared until the register is read. The current status of the
thermal shutdown condition can be read in the Status register.
0: The die temperature has not exceeded the overtemperature warning threshold.
