BQ29737DSER Description

Short technical summary and product information.

The Texas Instruments BQ29737DSER is a cost-effective integrated circuit designed for voltage and current protection in single-cell Li-ion and Li-Polymer battery applications. It provides essential protection functions including overcharge detection (OVP), over-discharge detection (UVP), charge overcurrent detection (OCC), discharge overcurrent detection (OCD), and load short-circuit detection (SCP).

 

This device features FET drive outputs for CHG and DSG FETs, and utilizes voltage sensing across external FETs for accurate overcurrent protection (OCP) with typical accuracy within ±5mV. It operates with low current consumption in normal mode (4µA) and shutdown mode (100nA).

 

The BQ29737DSER is factory programmed with fault protection thresholds, trigger timers, and recovery timers. It supports zero voltage charging for depleted batteries and operates within a temperature range of -40°C to +85°C. The IC is housed in a compact 6-pin WSON package suitable for surface mounting.

 

Key applications include tablet PCs, mobile handsets, and handheld data terminals where reliable battery protection is critical.
