8.6.3 (02h) ON_OFF_CONFIG

CMD Address02h
Write Transaction:Write Byte
Read Transaction:Read Byte
Format:Unsigned Binary (1 byte)
Phased:No
NVM Back-up:EEPROM
Updates:On-the-fly

The (02h) ON_OFF_CONFIG command configures the combination of enable pin input and serial bus commands needed to enable/disable power conversion. This includes how the unit responds when power is applied to PVIN.

7:5ReservedR000bNot used and always set to 0.
4PURWNVM0b: Unit starts power conversion any time the input power is present regardless of the state of the CONTROL pin.
1b: Act on CONTROL. (01h) OPERATION command to start/stop power conversion, or both.
3CMDRWNVM0b: Ignore (01h) OPERATION Command to start/stop power conversion.
1b: Act on (01h) OPERATION Command (and CONTROL pin if configured by CP) to start/stop power conversion.
2CPRWNVM0b: Ignore CONTROL pin to start/stop power conversion. The UVLO function of the EN/UVLO pin is not active when CONTROL pin is ignored.
1b: Act on CONTROL pin (and (01h) OPERATION Command if configured by bit [3]) to start/stop power conversion.
1POLARITYRWNVM0b: CONTROL pin has active low polarity. The UVLO function of the EN/UVLO pin cannot be used when CONTROL has active low polarity.
1b: CONTROL pin has active high polarity.
0DELAYRWNVM0b: When power conversion is commanded OFF by the CONTROL pin (must be configured to respect the CONTROL pin as above), continue regulating for the (64h) TOFF_DELAY time, then ramp the output voltage to 0 V, in the time defined by (65h) TOFF_FALL.
1b: When power conversion is commanded OFF by the CONTROL pin (must be configured to respect the CONTROL pin as above), stop power conversion immediately.

For the purposes of (02h) ON_OFF_CONFIG, the device pin EN/UVLO is the CONTROL pin.

Attempts to write (02h) ON_OFF_CONFIG to any value other than those explicitly listed above 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.
