TPS25750: Operation when combined with BQ25792RQMR

Yuta Nishie

Part Number: TPS25750

Tool/software:

Hi,

After starting the application on battery power, the IC does not recognize USB and does not charge even though USB is connected. Circuitwise, the TPS25750DRJKR and BQ25792RQMR are connected.

Could you tell me the possible cause? When there is no USB connection (battery power only), the TPS25750 power supply is only 3.3V. Does the above description cause the operation to be unstable?

The file created in LowRegion C file format using TPS25750_Application_Customization_Tool is incorporated into FW and PatchBundle is executed.

The waveform when the PatchBundle is active/inactive is shown in the following document.

Hi Nishie,

Thank you for reaching out!

Which GUI version was used to generate the binary file?
Please provide the json used
Could you provide schematics?
Does your application need to support BC1.2?

Best Regards,
