I’m very interested in the TI Battery Gauge bq27541-V200.
This part supports both I2C (2-wire) and HDQ interface (1-wire). From the datasheet “The bq27541 is shipped in the I2C mode. TI provides tools to enable the HDQ peripheral.” How do you get this part into HDQ mode? We will NOT have access to an I2C interface. How do we get the part to respond over the HDQ interface? Once configured for HDQ interface, does the device remain in HDQ interface during power-cycles
