The BQ29729DSER from Texas Instruments is an advanced single-cell battery protector IC specifically designed for Lithium-Ion and Li-Polymer battery applications. This device provides accurate monitoring and trigger thresholds for critical protection functions, including overcharge (OVP), over-discharge (UVP), charge overcurrent (OCC), discharge overcurrent (OCD), and load short-circuit (SCP).
It features voltage sensing across external FETs for precise overcurrent protection, with typical accuracy within ±5mV. The IC supports zero voltage charging for depleted batteries and includes factory-programmed fault protection thresholds. Operating in normal mode with a low ICC of 4µA and a shutdown Iq of 100nA, it is suitable for power-sensitive designs.
The BQ29729DSER is housed in a compact 6-pin WSON package with dimensions of 1.50mm x 1.50mm, making it ideal for space-constrained applications. It is designed for surface mount installation and operates within a temperature range of -40°C to 85°C.
