The BQ29706DSER from Texas Instruments is an integrated circuit designed for advanced single-cell battery protection in Lithium-ion and Lithium-polymer applications. This device provides accurate monitoring and trigger thresholds for overcurrent protection during high discharge or charge current operations, as well as battery overcharge conditions.
Key electrical features include an input voltage range from 0.3V to 12V and low current consumption in both normal (4µA) and shutdown (100nA) modes. The device monitors voltage across external power FETs for overcurrent protection with typical accuracy within ±5mV. It supports various fault detection mechanisms including overcharge (OVP), over-discharge (UVP), charge overcurrent (OCC), discharge overcurrent (OCD), and load short-circuit (SCP).
Packaged in a 6-pin WSON (1.5x1.5mm) or WFDFN, the BQ29706DSER is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device is programmed at the factory with fault protection thresholds, trigger timers, and recovery timers, simplifying design integration. It also supports zero voltage charging for depleted batteries.
This battery protector is ideal for portable electronics, power tools, and other battery-powered devices requiring reliable and robust battery safety management.
