BQ29729DSET

BATT PROT, LI-ION/LI-POL, WSON-6.

The BQ29729DSET is a cost effective voltage and current protector for single cell Li-ion and Li-polymer batteries in 6 pin WSON package. This device provides an accurate monitor and trigger threshold for overcurrent protection during high discharge/charge current operation or battery overcharge conditions. It uses a minimum number of external components to protect and provides the protection functions for Li-Ion/Li-polymer cells and monitors across the external power FETs for protection due to high charge or discharge currents. In addition, there is overcharge, depleted battery monitoring and protection. These features are implemented with low current consumption in NORMAL mode operation. It is used in tablet PC, mobile handset and handheld data terminals.
