Product details

Li-Ion stack protection — 2 to 4 series cells

The Texas Instruments BQ771601DPJT is a battery protection IC designed for Lithium-Ion packs configured in 2 to 4 series cells. Its sole protection function is over-voltage detection, tripping when any cell in the stack exceeds the threshold, which prevents the charger from driving a cell into an unsafe voltage region. Operating across -40°C to 110°C (TA), the device suits both consumer portable electronics and industrial battery packs that see temperature extremes during charge or discharge cycles.

Package and board-fit for the BOM

Supplied in an 8-WDFN exposed-pad package (8-WSON, 3x4 mm), the BQ771601DPJT is a surface-mount part.

Frequently asked questions

How do I get current pricing and availability for BQ771601DPJT?

Submit an RFQ against your BOM quantity.

When sourcing BQ771601DPJT, what's the closest functional second-source — BQ296217DSGT?

The BQ296217DSGT is a peer device from Texas Instruments with the same function (Battery Protection), cell count range (2 to 4), fault protection (Over Voltage), battery chemistry (Lithium Ion), and operating temperature range (-40°C to 110°C). Both are surface-mount, but the BQ296217DSGT uses a different package — verify the PCB footprint compatibility before substituting.

What compliance documentation does Texas Instruments provide for BQ771601DPJT?

The device is ROHS3 Compliant per the manufacturer's lifecycle record. For additional compliance documents (REACH, UL, IEC), refer to Texas Instruments' official product page or request them with your RFQ.
