Product details

Single-cell LiFePO4 charger with USB interface

The Texas Instruments BQ25071QWDQCRQ1 is a single-cell Lithium Iron Phosphate (LiFePO4) battery charger IC with a USB interface, designed for automotive environments qualified to AEC-Q100. It delivers a programmable constant charge current up to 1A, with the battery pack voltage fixed at 3.5V — the termination voltage for a single LiFePO4 cell.

10-WSON package with wettable flank

Housed in a 10-WFDFN exposed pad package (10-WSON, 3x2 mm), with surface-mount wettable flank terminals for automated optical inspection (AOI) of solder joints.

Frequently asked questions

Is BQ25071QWDQCRQ1 AEC-Q100 qualified?

Yes, the series designation is Automotive, AEC-Q100, qualifying it for automotive-grade applications including under-hood and chassis domains.

How to program the charge current on BQ25071QWDQCRQ1?

The charge current is constant and programmable — the datasheet details the resistor value selection between the ISET pin and ground to set the current up to the 1A maximum.

Is BQ25071QWDQCRQ1 a direct replacement for BQ25071?

The BQ25071QWDQCRQ1 is the automotive-grade variant of the base BQ25071. The suffix adds AEC-Q100 qualification and the wettable-flank package. Functionally they share the same charger core, but the automotive grade includes extended temperature range and qualification testing.
