Product details

Device function and chemistry fit

The BQ771803DPJT is a battery protection IC designed for lithium-ion chemistries, monitoring 2 to 5 series cells and triggering an over-voltage fault when any cell exceeds the threshold. Operating from -40°C to 110°C ambient, it covers the industrial temperature band needed for portable tools, power banks, and energy-storage packs that see warm enclosures.

Cut Tape works for prototype or low-quantity runs.

Frequently asked questions

How do I get current pricing and availability for BQ771803DPJT?

Submit an RFQ through this listing. Availability is verified against independent distribution stock at the time of inquiry.

What is the closest functional second-source to BQ771803DPJT?

The Texas Instruments BQ296217DSGT is a close functional peer — it also provides over-voltage protection for Li-Ion cells, but supports 2 to 4 cells instead of 2 to 5. Package and temperature range are similar (8-WSON, -40°C to 110°C). Verify the cell count requirement before substituting.

What compliance documentation does Texas Instruments provide for BQ771803DPJT?

Texas Instruments provides ROHS3 compliance certification for the BQ771803DPJT. No UL, IEC, or REACH documentation is listed in the available records. Standard TI datasheets and PCN notifications are available through the manufacturer's portal.
