The BQ29732DSET from Texas Instruments is an advanced single-cell battery protection integrated circuit for Lithium-ion and Lithium-polymer battery applications. This device provides robust protection against overvoltage, undervoltage, overcurrent during charge and discharge, and short-circuit conditions.
Key electrical specifications include a typical operating current of 4µA and a maximum input voltage of 8V. The overvoltage protection thresholds are set at 4.25V, 4.28V, and 4.4V, with battery overvoltage protection ranging from 3.85V to 4.6V. It supports 1-cell battery configurations and operates within a temperature range of -40°C to 85°C.
The BQ29732DSET is housed in a compact 6-WSON (1.5x1.5 mm) package and is designed for surface mounting. It features FET drive outputs and accurate voltage sensing for overcurrent protection. The device also includes fault detection for overcharge, over-discharge, charge overcurrent, discharge overcurrent, and load short-circuit conditions, along with zero voltage charging capability for depleted batteries.
