Switch-mode Li-ion Battery Charger In Pdip Or Soic Package

  The BQ2054 Lithium Ion FastCharge IC is designed to optimize charging of lithium ion (Li-Ion) chemistry batteries. A flexible pulse-width modulation Regulator allows the BQ2054 to control voltage and current during charging. The Regulator frequency is set by an external Capacitor for design flexibility. The switch-mode design keeps power dissipation to a minimum. The BQ2054 measures Battery temperature using an external thermistor for charge qualification. Charging begins when power is applied or on Battery insertion. For safety, the BQ2054 inhibits charging until the Battery voltage and temperature are within con-
