Hi,

I am using BQ27010 battery monitoring chip for monitoring Li-ion battery.

On my processor i have deidacted 1-wire interface while BQ27010 uses HDQ interface.

Please tell me whether it is possible to use 1-wire interface to interface to Bq27010 ?.

Thanking you.

Hello Apoorv

No, the Dallas 1-Wire protocol and the TI HDQ protocol are not compatible. You can use a dedicated GPIO port with firmware written to meet the HDQ timing or you can use a UART. The method for using a UART and other information on HDQ communication is described in TI application note SLUA 408.

Hello Bill,

Thanks a lot for the clarification.

I will go ahead with the GPIO implementation.
