Fault-Time

Icharge

Example :

If the sensing battery temperature is hot or cold, the charge current will reduce to half charge current. So, the fault-time

will increase to be double.

JEITA Battery Temperature Standard

CV regulation voltage will be changed in the following battery temperature ranges : 0

°C to 10°C and 45°C to 60°C.

This function can be disabled by A9.VSETH and A9.VSETC.

CC regulation current will be changed in the following battery temperature ranges : 0

°C to 10°C and 45°C to 60°C.

This function can be disabled by A9.ISETH and A9.ISETC.

Fault-Time

During the fast charge phase, several events may increase the charging time.

For example, the system load current may have activated the APPM loop which reduces the available charging current

or the device has entered thermal regulation because the IC junction temperature has exceeded TREG.

However, once the duration exceeds the fault-time, the CHG output pin will flash at approximately 4Hz to indicate a fault

condition and the charge current will be reduced to about 1mA.

There are four methods to release the Fault-time :



Re-plug power



Toggle EN



Enter/exit suspend mode



Remove Battery



OVP

The fault-time is inverse proportional to the charger current.
