Product details

Single-cell Li-Ion protection with integrated FET drive

The BQ29723DSET is a single-cell lithium-ion/polymer battery protection IC from Texas Instruments. It monitors one series cell and triggers protection for over-current, over-voltage, under-voltage, and short-circuit conditions. The protection thresholds and timing are set internally, so no external programming resistors are needed — the IC operates as a standalone protector in the battery pack.

6-WSON package and board-fit

Housed in a 6-WFDFN package with a 1.5x1.5 mm body (supplier device package 6-WSON), the BQ29723DSET is a surface-mount device suited for compact battery packs where PCB area is tight.

No end-of-life notice or last-time-buy window is in effect.

Frequently asked questions

What is the BQ29723DSET used for?

It is a single-cell lithium-ion/polymer battery protection IC that monitors over-current, over/under-voltage, and short-circuit faults. It is typically placed on the battery protection circuit module (PCM) inside a Li-Ion pack.
