VIN_ON command sets the value of the input voltage, in Volts, at which the unit should start power conversion.
|LEGEND: R/W = Read/Write; R = Read only|
Linear format two’s complement exponent, -2
Linear format two’s complement mantissa. Refer to the following text for more information.
Attempts to write Section 7.6.28 to any value outside those specified as valid will be considered invalid/unsupported data and cause the TPSM8D6C24 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
Section 7.6.28 and Section 7.6.29 have limited hardware range and resolution as well as limited NVM allocation. While the command will accept any binary value within the valid range, values not exactly represented by the hardware resolution will be rounded down to the next lower supported threshold for implementation or upon restore from NVM during Power-On Reset or Section 7.6.8. Section 7.6.28 hardware supports all values from 2.50 V to 18.25 in 0.25-V steps.
Note that the LOW_VIN fault condition is masked until the sensed input voltage exceeds the VIN_ON threshold for the first time following a power-on reset. Control/Enable pin toggles and EEPROM store/restore operations do not reset this masking.
