Part Number: TIDA-01582
Other Parts Discussed in Thread: BQ25960HEVM, , BQ25890, BQ25970, BQ25638, BQ25960H, BQ25611D, PMP23456

Tool/software:

Hello,

Our team is currently planning the development of a new product that will utilize a single-cell Li-Po high-capacity battery. We are exploring solutions that can help us evaluate the concept, including Source-to-Sink energy negotiations and fast charging using the USB-C PD PPS protocol. As part of this initiative, we are seeking an Evaluation Board (EVB) that incorporates the following features:

USB-C PD Controller for managing power delivery and protocol compliance.
2-Level Buck (2LBk) Charger with NVDC can operate during trickle charging, pre-charging, or constant voltage (CV) stages.
Switched-Cap Chargers are optimized for constant current (CC) charging stages.

During our research, we found several options on your website, including the BQ25960HEVM and TIDA-01582, BQ25890, and BQ25970, which seem to align with our requirements.

Could you please assist us in understanding:

The features and suitability of these EVBs for our intended application,
The availability of these EVBs, and
Pricing information for procurement.

Additionally, we request your guidance in summarizing relevant product support for 2-level buck + switched-cap Div2 battery chargers that meet our design and evaluation needs.

Best regards,

Vitaliy

Hi Vitaliy,

What do you mean by a two level buck converter? We have a reference design, TIDA-01582, that incorporates the PD controller and the switch-cap charger with the BQ25890 on board.

Regards,

Mike Emanuel

Hi Mike,

Thanks, it will work for me.

Could you please help me?

Where can I purchase this EVB, at what price, and what is the stock availability?

Hello Vitaliy,

Unfortunately we do not sell that board anymore, we just have the design files.

We have the BQ25970EVM-893 which has 2 BQ25970s on board (no PD-Controller), as well as BQ25960H with 2 BQ25960HEVM and BQ25611D (no PD-Controller) and PMP23456 with BQ25638 and PD-Controller.

Regards,

Mike Emanuel

Hi Mike,

David Mckinney is Motorola FAE.

If I understand you right, TI today does not have sellable EVB solution that may simulate cellular phone 1S battery charging solution based on USB-PD controller + switch-cap charger that can negotiate the ADPO (PPS) profile and charge the 1S battery on high rate?

Thanks

Hi Vitaliy,

We are hoping to resolve this offline.
