Description

[15:0]

Offset trim

R/W

Twos complement integer used to apply a fixed offset voltage to the VOUT_COMMAND value.

VOUT_CAL_OFFSET

The VOUT_CAL_OFFSET command is used to apply a fixed offset voltage to the VOUT_COMMAND value.

Offset trim

R/W

Twos complement integer used to apply a fixed offset voltage to the VOUT_COMMAND value.

VOUT_MAX

The VOUT_MAX command sets an upper limit on the output voltage. Exponent N is set using VOUT_MODE[4:0].

Description

[15:0]

Mantissa-Y

R/W

Sets the output voltage upper limit. 16-bit unsigned integer Y value for linear data format (V = Y × 2N).

VOUT_TRANSITION_RATE

When the device receives a VOUT_COMMAND or OPERATION command that causes the output voltage to change, this command sets

the output transition rate (or slew rate), in mV/μs, at which the VS± pins change voltage.

Exponent-N

R/W

Twos complement N-exponent used in linear data format (X = Y × 2N).

[10:0]

Mantissa-Y

R/W

Twos complement Y-mantissa used in linear data format (X = Y × 2N).

VOUT_DROOP

The VOUT_DROOP command sets the rate, in mV/A, at which the output voltage decreases (or increases) with increasing (or

decreasing) output current.

Exponent-N

R/W

Twos complement N-exponent used in linear data format (X = Y × 2N).

[10:0]

Mantissa-Y

R/W

Twos complement Y-mantissa used in linear data format (X = Y × 2N).

VOUT_SCALE_LOOP

The VOUT_SCALE_LOOP command sets the gain (KR) by which the commanded voltage (VOUT) is scaled to generate the internal

reference voltage (VREF). VREF = VOUT × KR, where KR = Y × 2N.

Exponent-N

R/W

Twos complement N-exponent used in linear data format (X = Y × 2N).

[10:0]

Mantissa-Y

R/W

Twos complement Y-mantissa used in linear data format (X = Y × 2N).

VOUT_SCALE_MONITOR

The VOUT_SCALE_MONITOR command sets the gain (KVOUT) by which the sensed output voltage at the DUT (VOUT_DUT) is scaled to

generate the reading for the READ_VOUT command. READ_VOUT = VOUT_DUT × KVOUT, where KVOUT = Y × 2N.
