Android charging battery drivers

electronic15 — Mon, 18 May 2020 15:10:57 GMT

Hi everyone,

We are starting a new design based on the i.MX8 Mini processor which will be a portable device powered by a Li-On 3.7v battery pack. This device will run Android 9 OS. The battery will be charged through a USB 2.0 Type-C interface and we need to solve the USB PD, charging battery, and fuel gauge battery.

Is there any IC(s) to solves those issues compatible with the OS or whose drivers are available? (we would like to avoid developing the drivers)

Thanks!

Hello Gonzalo,

Our i.MX8MM-EVK doesn't support Charger IC, BUT On our I.MX6DL-SabreSD board, charger IC MAX8903C is supported, so you can refer to it's schematic and charger driver in android.

Attachment is it's schematic.

Or your can also select charger ICs from other providers, basically, they also provide you corresponding drivers.

Hope the information is helpf to you!

Have a great day!

B.R,

Weidong

Thank you Wigros, it helps me a lot. I already saw a few options from MAXIM so I'm going to inquire into it a bit more.

Regards.
