Hello,

We do not have a specific driver created for this device. However, there is third party driver software available here: https://chromium.googlesource.com/chromiumos/platform/ec/+/master/driver/charger

Keep in mind that this software was not developed nor is it supported by TI, so please use are your own discretion.

Regards,

Joel H

Hi there,

We have default setting for all registers, you don't need to provide I2C setting for all of them. Assume you are using 0.5C rate charging(2.6A fast charging current). The hardware and I2C configuration you need to change is below(Please also pull CELL_BATPRESZ to 55% of VDDA voltage):

1,Please also pull CELL_BATPRESZ to 55% of VDDA voltage

2,Set charge current at REG0x03/02h to 0A28h (2.6A)

3, Set charge voltage at REG0x05/04h to 2EE0h(12.000V)

4, Set minimum system voltage at REG0x0Dh to 23h (8.96V)

Regards
