VOUT_MARGIN_HIGH [0x25]
Range limits (max/min): 13.2/8.1
Units: volt
Command support: read/write support, full functionality except “Ignore faults”.
Note: Range cross-check - value must be greater than VOUT_MARGIN_LOW value.
VOUT_MARGIN_LOW [0x26]
Range limits (max/min): 13.2/8.1
Units: volt
Command support: read/write support, full functionality except “Ignore faults”.
Note: Range cross-check - value must be less than VOUT_MARGIN_HIGH value.
VOUT_DROOP [0x28]
Factory default: 0 (No droop); 15 (Parallel operation)
Range limits (max/min): 50/0
Units: mv/A
Command support: All functionality
VIN_ON [0x35]
Range limits (max/min): 46/32
Units: volt
Command support: All functionality
Note: Special interlock checks between VIN_ON and VIN_OFF maintain a hysteresis gap of 2V minimum and do not allow the OFF
level to be higher than and ON level
VIN_OFF [0x36]
Range limits (max/min): 46/32
Units: volt
Command support: All functionality
Note: Special interlock checks between VIN_ON and VIN_OFF maintain a hysteresis gap of 2V minimum and do not allow the OFF
level to be higher than and ON level
VOUT_OV_FAULT_LIMIT [0x40]
Range limits (max/min): 15.99/10.9 (See note 2)
Units: volt
Command support: All functionality
Note:
1. Range cross- check – value must be greater than VOUT_COMMAND value.
2. The maximum OV Fault Limit equals the output set point plus 3V, up to 15.99V. This is an automatic module protection
feature that will override a user-set fault limit if the user limit is set too high.
VOUT_OV_FAULT_RESPONSE [0x41]
Command support:
‐ Response settings (bits RSP0:1) – only a setting of 10, 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 VOUT_OV_FAULT_RESPONSE command are;
‐ The unit shuts down in response to a VOUT over voltage condition.
‐ The unit will continuously restart (normal startup) while the VOUT over voltage 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.
