JEITA Li-Ion Battery Temperature Charging Specification
The ADP5061 is compliant with the JEITA1 and JEITA2 Li-Ion
battery charging temperature specifications as outlined in Table 14
and in Table 16, respectively.
JEITA function can be enabled via the I
2
C interface and,
optionally, the JEITA1 or JEITA2 function can be selected in
I
2
C. Alternatively, the JEITA1 or JEITA2 can be set as enabled
to default by factory programming.
When the ADP5061 identifies a hot or cold battery condition,
the ADP5061 takes the following actions:
• Stops charging the battery.
• Connects or enables the battery isolation FET such that the
ADP5061 continues in LDO mode.
