Other Parts Discussed in Thread: BQ25890,
Tool/software:
The differences on the BQ25890H compared to the BQ25890 are as follows.
- At startup in charge mode the H version not only does regular D+/D- detection the same as BQ25890, but also allows the host to control D+/D- voltage levels via REG01, thereby allowing negotiations with additional adapter types.
- On the H version in OTG boost mode the host can enable/disable PFM mode operation via REG0A[3].
- On the H version minimum battery voltage for OTG boost mode operation can be changed from 2.9V max to 2.6V max via REG03[0].
- Beyond register map differences in REG01, REG03, and REG0A all other registers are defined the same on BQ25890 and BQ25890H.
