IOUT_OC_FAULT_LIMIT, IOUT_OC_WARN_LIMIT and IOUT_UC_FAULT_LIMIT
I

supervisor fault and warning limits.
IOUT_OC_FAULT_LIMITED is internally limited to values greater or equal to zero. The register readback value always
returns what was last written and does not reflect internal limiting.
IOUT_UC_FAULT_LIMITED is internally limited to values less than zero. The register readback value always returns
what was last written and does not reflect internal limiting.
MFR_IOUT_CAL_GAIN_TC
The MFR_IOUT_CAL_GAIN_TC is a paged command that sets the temperature coefficient of the IOUT_CAL_GAIN
register value in ppm/°C. This command uses the temperature measured by the external temperature diode for the
associated page.
Refer to IOUT_CAL_GAIN for details on proper usage.
MFR_IOUT_CAL_GAIN_TC Data Contents
BIT(S) SYMBOL OPERATION
b[15:0] Mfr_iout_cal_gain_tc 16-bit twos complement integer representing the temperature coefficient.
Value = Y where Y = b[15:0] is a twos complement.
Example:
Mfr_iout_cal_gain_tc = 3900ppm
For b[15:0] = 0x0F3C
Value = 3900
