8.6.31 (38h) IOUT_CAL_GAIN

CMD Address	38h
Write Transaction:	Write Word
Read Transaction:	Read Word
Format:	SLINEAR11, per CAPABILITY
Phased:	No
NVM Back-up:	EEPROM
Updates:	On-the-fly

(38h) IOUT_CAL_GAIN is used to trim the gain of the output current reported by the READ_IOUT command. The value is a unitless gain factor applied to the internally sensed current measurement. It defaults to a value of 1.

Attempts to write (38h) IOUT_CAL_GAIN to any value outside those specified as valid will be considered invalid/unsupported data and cause the TPSM8S6C24 to respond by flagging the appropriate status bits and notifying the host according to the PMBus 1.3.1 Part II specification section 10.9.3.

Command Resolution and NVM Store/Restore Behavior

The (38h) IOUT_CAL_GAIN command is implemented using the TPSM8S6C24 internal telemetry system. As a result, the value of this command can be programmed with very high resolution using the linear format. However, the TPSM8S6C24 provides only limited NVM-backed options for this command. Following a power-cycle or NVM Store/Restore operation, the value will be rounded to the nearest 1/64 with a maximum supported value of 1.984 (1 63/64).
