BQ25619E: Top Off timer not double at cool temperature

Part Number: BQ25619E

Tool/software:

Hello,

I'm testing charging a battery at cool temperature (5°C) and measuring current going to the battery.

The programmed top off timer is 30min.

I expected that at cool temperature the safety timer would be slowed down by 2 so the top off timer would also be slowed down (1 hour).

But charging still stops after 30 minutes.

Here is the i2C register I'm reading just before the charge is stopped:

REG00 0x05
REG01 0x1A
REG02 0x8A
REG03 0x00
REG04 0x9D
REG05 0x8F
REG06 0x66
REG07 0x55
REG08 0x3C
REG09 0x03
REG0A 0x88
REG0B 0x44
REG0C 0xA5

Do you know why top off timer is not becoming 1hour at cool temperature?

Thanks
