Digital Voltage Monitoring and Power-Good
Output
The voltage at the load (MON input) is sampled by the
internal ADC. The MON full-scale voltage can be set to
16V, 8V, 4V, or 2V by writing to register mon_range. The
default range is 16V (Tables 16 and 17).
The most recent voltage-conversion results can be read
from the adc_mon_msb and adc_mon_lsb registers (see
Tables 18 and 19).
Digital Undervoltage- and Overvoltage-
Detection Thresholds
The most recent voltage values are continuously com-
pared to four programmable limits, comprising two
undervoltage (UV) levels (see Tables 20 to 23) and two
overvoltage (OV) levels (see Tables 24 to 27).
If PG is asserted and the voltage is outside the warning
limits, the ALERT output is asserted low. Depending on
the status of the prot[] bits in register status1[7:6], the
