IOUT_OC_FAULT_LIMIT [0x46]
Range limits (max/min): 41.5/20
Units: amp
Command support: All functionality
Note: Range cross-check – value must be greater than IOUT_OC_WARN_LIMIT value.
IOUT_OC_FAULT_RESPONSE [0x47]
Command support:
‐
Response settings (bits RSP0:1) – only settings of 11, unit shuts down and responds according to the retry settings
below, is supported.
‐
Retry settings (bits RS0:2) – only settings of 000 (unit does not attempt to restart on fault) and 111 unit continuously
restarts (normal startup) while fault is present until commanded off, bias power is removed or another fault
condition causes the unit to shutdown.
‐
Delay time setting (bits 0-2) – only DT0:2 = 0 (no delay) supported.
Default Settings: The default settings for the IOUT_OC_FAULT_RESPONSE command are;
‐
‐
The unit shuts down in response to an IOUT over current condition.
The unit will continuously restart (normal startup) while the IOUT over current condition is present until it is
commanded off, bias power is removed or another fault condition causes the unit to shutdown.
The shutdown delay is set to 0 delay cycles.

OT_FAULT_RESPONSE [0x50]
Command support:
‐
Response settings (bits RSP0:1) – only setting of 10, unit shuts down and responds according to the retry settings
below.
‐
Retry settings (bits RS0:2) – only settings of 000 (unit does not attempt to restart on fault) and 111 unit continuously
restarts (normal startup) while fault is present until commanded off, bias power is removed or another fault
condition causes the unit to shutdown.
‐
Delay time setting (bits 0-2) – only DT0:2 = 0 (no delay) supported.
Default Settings: The default settings for the OT_FAULT_RESPONSE command are;
‐
‐
The unit shuts down in response to an over-temperature condition.
The unit will continuously restart (normal startup) while the over-temperature condition is present until it is
commanded off, bias power is removed or another fault condition causes the unit to shutdown.
The shutdown delay is set to 0 delay cycles.
