    BQ2057TTS Product overview

    The BQ2057TTS is a low dropout linear 2-cell Li-ion Charge Controller with 8.2V AutoComp. It is designed for cost-sensitive and compact portable electronics. They combine high-accuracy current and voltage regulation, battery conditioning, temperature monitoring, charge termination, charge-status indication and AutoComp charge-rate compensation in a single 8-pin IC. The BQ2057 continuously measures battery temperature using an external thermistor. For safety, it inhibits charge until the battery temperature is within user-defined thresholds. It charges the battery in three phases: conditioning, constant current and constant voltage. If the battery voltage is below the low-voltage threshold, V(min), It pre-charges using a low current to condition the battery. The conditioning charge rate is approximately 10% of the regulation current. The conditioning current also minimizes heat dissipation in the external pass-element during the initial stage of the charge.
