PROTECTION REGISTER
The Protection Register consists of flags that indicate protection circuit status and switches that give
conditional control over the charging and discharging paths. Bits OV, UV, COC and DOC are set when
corresponding protection conditions occur and remain set until cleared by the host system. The default
values of the CE and DE bits of the Protection Register are stored in lockable EEPROM in the
corresponding bits in address 30h. A Recall Data command for EEPROM block 1 recalls the default
values into CE and DE. The format of the Protection Register is shown in Figure 9. The function of each
bit is described in detail in the following paragraphs.
PROTECTION REGISTER FORMAT Figure 9
Address 00
bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0
OV UV COC DOC CC DC CE DE
OV – Overvoltage Flag. When set to 1, this bit indicates the battery pack has experienced an overvoltage
condition. This bit must be reset by the host system.
UV – Undervoltage Flag. When set to 1, this bit indicates the battery pack has experienced an
undervoltage condition. This bit must be reset by the host system.
