VDD/VCORE OVLO

The ADP1055 has built-in overvoltage protection (OVP) on its

supply rails. When the VDD or VCORE voltage rises above the

OVLO threshold, the response can be programmed using

OVP fault occurs, the response be set to download the EEPROM

before restarting the ADP1055. All features related to the OVLO

function—such as debounce, fault ignore, and download EEPROM

upon receiving a fault condition—are programmable using

VDD overvoltage is ignored when the device is downloading

information from the EEPROM, even if the overvoltage occurs

during the initial power-up or due to the setting of Register

0xFE4D[6]. VDD overvoltage is recognized as a fault only after

the EEPROM download is complete. The ADP1055 has a 4 ms

idle time after an EEPROM download.

If the VDD overvoltage occurs during the ramp-up of VDD and

the ADP1055 has not initiated the EEPROM download, the

device responds according to the default setting of Bit 7 in
