The BQ2057TSN from Texas Instruments is an advanced linear charger management IC specifically designed for single-cell and two-cell Lithium-ion and Lithium-polymer battery packs. It is ideal for cost-sensitive, compact portable electronics.
This IC integrates high-accuracy current and voltage regulation, battery conditioning, temperature monitoring, charge termination, charge-status indication, and AutoComp™ charge-rate compensation. It requires minimal external components and offers a low 0.3V drop voltage to minimize heat dissipation. The voltage regulation accuracy is better than ±1% at preset voltages.
The BQ2057TSN supports programmable charging current and features high-side or low-side current detection. It includes integrated cell conditioning to recover deeply discharged cells and minimize heat during the initial charging phase. The device operates within a temperature range of -20°C to 70°C (TA) and is available in an 8-SOIC package suitable for surface mounting.
Applications for the BQ2057TSN include emergency call systems, telematics control units, automotive telematics, gaming and computer accessories, portable medical devices, and EPOS card readers.
