CONTROL REGISTER
The format of this register is shown in Figure 12. Bits 5 and 4 are read-only and return logic 0 when read.
The function of each bit is described in detail in the paragraphs below.

LPM
- Low Power Mode. Setting this bit to logic 1 puts the DS2441 into Low Power Mode. See the
section on Low Power Mode for more details. The default value is 0 (inactive).
RFSH -
Refresh Mode. Setting this bit to logic 1 puts the DS2441 into Refresh Mode. See the section on
Refreshing Undervoltage Packs for more information. A high-to-low transition on the DQ pin clears this
bit to logic 0 and disables Refresh Mode.
CHG
-
State of
CHG
output pin. This read-only bit mirrors the state of the
CHG
output pin.
DCHG
-
State of
DCHG
output pin. This read-only bit mirrors the state of the
DCHG
output pin.
CHE
- Charge enable. Writing logic 0 to this bit disables charging (
CHG
output driver off, external
charge FET off) regardless of cell or pack conditions. Writing logic 1 to this bit enables charging, subject
to override by the presence of any protection conditions.
DCHE
- Discharge enable. Writing logic 0 to this bit disables discharging (
DCHG
output driver off,
external discharge FET off) regardless of cell or pack conditions. Writing logic 1 to this bit enables
discharging, subject to override by the presence of any protection conditions.
