Hi Yamazaki-san,
Hiroaki Yamazaki said: In fact, I don't need a complete PPS. I just need to switch between 5V3A and 15V3A. Is it possible to prepare these two power supplies, input them to the PPHV and PP5V of the TPS25751, and switch the voltage by turning…

Buck-only mode would make sense for your application.

Hello Sudheer,
The BQ25758 will go back to CC mode once the output load current is reduced below IOUT_REG. At this moment, VOUT_Measured=VOUT_REG and the BQ25758 will go back into CV mode.
Let me know if you have any questions about this.
Best Regards…
Hello Sudheer,
Sudheer Gaddipati said: Is there any register which indicates that the capacitors drained fully ?
The capacitors should drain pretty fast. The charger can also provide an output load while EN_IBAT_LOAD=1.
There are a few ways:
The first…
Part Number: BQ25758 Other Parts Discussed in Thread: BQ25756 , Tool/software: Hi team,
Customer ask what is the difference between BQ25756 and BQ25758,
Can you show the key differences of these two devices?
Is BQ25758 only can work with 14 cells battery…
Part Number: BQ25758 Tool/software: hi,
A my account needs a bidirectional converter with below spec. Can BQ25758 setting in buck-only mode(only two MOSFETs(Q1 & Q2) are used) support reverse mode?
Forward way: From input to output; input voltage…
Part Number: BQ25758 Tool/software: Hi ,
When using BQ25758 for PPS 21V @5A output, E-Loader Set CV Mode, when CV is set to 20V, BQ25758 will trigger VAC UVP.
How to implement the PPS Constant Current function?
ACUV has been Shorted to PGND.
Hi Aya,
Thanks for the answers.

Part Number: BQ25758 Tool/software: Why is it not possible to use the IC with GaN FET's? We tried to use it with the Infineon (GaN Systems) GS61004B and always destroyed the IC..is there a reason for that? We used this configuration from the datasheet…
