Battery Temperature from I2C

If a microcontroller has another accuracy temperature sense in

system, it can select the temperature source via the I2C setting

and write the temperature value to the BAT_TEMP[5:0] bits.

The I2C source battery temperature range is between −2°C

and +61°C.

JEITA Li-Ion Battery Temperature Charging Specification

The charge of the ADP5350 is compliant with the JEITA Li-Ion

battery charging temperature specifications, as shown in

Table 14.

The JEITA function is enabled via the I2C interface. When the

ADP5350 detects a JEITA cool condition, charging current is

reduced according to Table 13.

When the ADP5350 identifies a hot or cold battery condition,

the battery isolation FET turns on and the dc-to-dc regulator

shuts down. In this condition, the battery provides the VISOS supply.
