Name
Local OVP
R/W
R/W
Description
Local OVP Trim. This range is programmable so that the Local OVP flag can be set when 1.9 V to
2.85 V appears at the VLS pin when the nominal voltage is 2 V. Each LSB corresponds typically to
an increase of 3.7 mV. See the Local Overvoltage specifications in Table 1.
