The BQ29701DSET from Texas Instruments is a cost-effective integrated circuit designed for advanced single-cell battery protection in Lithium-ion and Lithium-polymer applications. This device accurately monitors and triggers thresholds for overcurrent protection during high discharge or charge current operations, as well as for battery overcharge conditions.
Key protection features include overcharge detection (OVP), over-discharge detection (UVP), charge overcurrent detection (OCC), discharge overcurrent detection (OCD), and load short-circuit detection (SCP). It also supports zero voltage charging for depleted batteries. The device operates within a wide input voltage range of 0.3V to 12V and maintains functionality across an operating temperature range of -40°C to 85°C.
Packaged in a compact 6-WSON (1.5x1.5mm) surface-mount package, the BQ29701DSET is suitable for space-constrained designs. Its low normal mode supply current of 4µA and shutdown current of 100nA contribute to power efficiency in battery-powered devices. The IC utilizes voltage sensing across external FETs for precise overcurrent protection, with typical accuracy within ±5mV.
