READ_VOUT (8Bh)
The READ_VOUT command is a standard PMBus
™
command that returns the 12-bit measured value of the
output voltage. Reading this register should use the coefficients shown in
. Accesses to this command
should use the PMBus
™
read word protocol. This value is also used internally for the VOUT Under Voltage
Warning detection.

READ_IIN (89h)
The READ_IIN command is a standard PMBus
™
command that returns the 12-bit measured value of the input
current. Returns instantaneous current. Reading this register should use the coefficients shown in
Accesses to this command should use the PMBus
™
read word protocol. This value is also mirrored at (D1H)

READ_PIN (97h)
The READ_IIN command is a standard PMBus
™
command that returns the 12-bit measured value of the input
current. Returns average power Reading this register should use the coefficients shown in
. Accesses to
this command should use the PMBus

READ_TEMPERATURE_1 (8Dh)
The READ_TEMPERATURE _1 command is a standard PMBus
™
command that returns the signed value of the
temperature measured by the external temperature sense diode. Reading this register should use the coefficients
shown in
shown in
. Accesses to this command should use the PMBus
™
read word protocol. This value is also
used internally for the Over Temperature Fault and Warning detection. This data has a range of -256°C to +
255°C after the coefficients are applied.
255°C after the coefficients are applied.

MFR_ID (99h)
The MFR_ID command is a standard PMBus
™
command that returns the identification of the manufacturer. To
read the MFR_ID, use the PMBus
™
block read protocol.
