BQ24003
Overview
The bq2400x series ICs are advanced Li-Ion linear charge management devices for highly integrated and space-limited applications. They combine highaccuracy current and voltage regulation; FET passtransistor and reverse-blocking Schottky; battery conditioning, temperature, or input-power monitoring; charge termination; charge-status indication; and charge timer in a small package.
- Highly Integrated Solution With FET Pass Transistor and Reverse-Blocking Schottky and Thermal Protection
- Integrated Voltage and Current Regulation With Programmable Charge Current
- High-Accuracy Voltage Regulation (±1%)
- Ideal for Low-Dropout Linear Charger Designs for Single-Cell Li-Ion Packs With Coke or Graphite Anodes
- Up to 1.2-A Continuous Charge Current
- Safety-Charge Timer During Preconditioning and Fast Charge
- Integrated Cell Conditioning for Reviving Deeply Discharged Cells and Minimizing Heat Dissipation During Initial Stage of Charge
- Optional Temperature or Input-Power Monitoring Before and During Charge
- Various Charge-Status Output Options for Driving Single, Double, or Bicolor LEDs or Host-Processor Interface
- Charge Termination by Minimum Current and Time
