BQ24133EVM-715-15V (TEXAS INSTRUMENTS)

The BQ24133EVM-715-15V is for evaluating the bq24133 synchronous battery charger. The bq24133 is highly integrated stand alone lithium ion and lithium polymer switch mode battery charger with two integrated N channel power MOSFETs. It offers a constant frequency synchronous PWM controller with high accuracy regulation of input current, charge current, and voltage. It closely monitors the battery pack temperature to allow charge only in a preset temperature window. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. A programmable charge timer offers a safety back up. The bq24133 automatically restarts the charge cycle if the battery voltage falls below an internal threshold, and enters a low quiescent current sleep mode when the input voltage falls below the battery voltage.
