VOUT_OV_WARN_LIMIT (continued)
VOUT_UV_WARN_LIMIT
IOUT_OC_FAULT_LIMIT
IOUT_OC_WARN_LIMIT
OT_FAULT_LIMIT
Doc ID 13286 Rev 2
The VOUT_OV_WARN_LIMIT command sets the
value of the output voltage at the sense or output
pins that causes an output voltage high warning.
This value is typically less than the output
overvoltage threshold.

VOUT_UV_WARN_LIMIT
43h
The VOUT_UV_WARN_LIMIT command sets the
value of the output voltage at the sense or output
pins that causes an output voltage low warning.
This value is typically greater than the output
undervoltage fault threshold

IOUT_OC_FAULT_LIMIT
46h
The IOUT_OC_FAULT_LIMIT command sets the
value of the sense output current, in amps (literal
format), that causes an overcurrent fault.
