The VIN_ON command sets the value of the PVIN input voltage, in Volts, at which the unit starts power conversion.

00b: ON threshold is PVIN = 10 V. 01b: ON threshold is PVIN = 9 V 10b: ON threshold is PVIN = 8 V 11b: ON threshold is determined by both PVIN and VCC conditions. When this option is selected, both PVIN > 2.55 V and VCC > 3.8 V conditions have to be satisfied to enable the power conversion. |
Note that the PVIN_UVF condition in (7Ch) STATUS_INPUT register is masked until the sensed input voltage exceeds the VIN_ON threshold for the first time following a power-on reset. The EN pin toggles and NVM store or restore operations do not reset this masking.
