Other Parts Discussed in Thread: TPS25750, , BQ25792, TUSB422
Dual input of solar energy and type C, type C is preferred, and there will be built-in battery and expanded backup battery.
1, The D+ and D - of BQ25798 support the detection of BC1.2. When using Type C, is it can directly connect DP and DM Pin, or use the CC control logic chip, such as TPS25750?
2, Whether the D+ and D - of Q25798 can also be used as data channels to transmit data while performing USB PD detection?
3, When solar energy and type C dual input are used, back-to-back MOS tubes are used on each channel. Is there current backflow when there is voltage input at the same time, for example, 21.7V of solar energy backflow current into 5V of type C?
4, For the battery part, 2 series of built-in batteries are the default ones of the system, and 2 series of extended batteries are pluggable. Can they be designed with 2S2P? Does plugging and unplugging of extended batteries affect BQ25798?
Waiting for your reply.
