OT_WARN_LIMIT [0x51]
Range limits (max/min): 125/25
Units: degrees C.
Command support: All functionality
Note: Range cross-check – value must be less than OT_FAULT_LIMIT value.
VIN_OV_FAULT_LIMIT [0x55]
Range limits (max/min): 90/48
Units: volt
Command support: All functionality
VIN_OV_FAULT_RESPONSE [0x56]
Command support:
Response settings (bits RSP0:1) – only settings of 11 (The device’s output is disabled while the fault is present.) and 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).
‐ Delay time setting (bits 0-2) – only DT0:2 = 0 (no delay) supported.
Default Settings: The default settings for the VIN_OV_FAULT_RESPONSE command are;
‐ The unit shuts down in response to a VIN over voltage condition.
‐ The unit will continuously restart (normal startup) while the VIN over voltage condition is present until it is
commanded off, bias power is removed, the VIN over voltage condition is removed, or another fault condition
causes the unit to shutdown.
‐ The shutdown delay is set to 0 delay cycles.
