Hi,
My customer are using BQ25883 for Bluetooth wireless speakerphone, they want BQ25883 automatic detect tow input source (SDP/CDP/DCP), if it is work as a DPDT switch is applied to exchange the USB path(As bellow show) and set AUTO_INDET_EN = 1. If there are extra setting is needed?
Thanks!
Hi Jim,
Automatic D+/D- detection is enabled by default. Therefore, when VBUS is plugged in, the BQ25883 will automatically run the D+/D- input source type detection. This is part of the power-up sequence described in Section 8.3.3 in the datasheet, so you do not need any extra steps to run the D+/D- detection. Afterwards, the host MCU can change the input current limit setting by writing to the IINDPM register, if desired.
Best regards,
Angelo
