TEXAS INSTRUMENTS  BQ24103ARHLR  Battery Charger for 2 Cells of Li-Ion battery, 16V input, 8.4V/2 A charge, QFN-20

Product Overview

The BQ24103ARHLR is a highly integrated Li-ion and Li-polymer switch-mode Charge Management Device targeted at a wide range of portable applications. The bqSWITCHER™ series offers integrated synchronous PWM controller and power FETs, high-accuracy current and voltage regulation, charge preconditioning, charge status and charge termination. The system-controlled version provides additional inputs for full charge management under system control. The bqSWITCHER™ charges the battery in three phases: conditioning, constant current and constant voltage. Charge is terminated based on user- selectable minimum current level. A programmable charge timer provides a safety backup for charge termination. The bqSWITCHER™ automatically restarts the charge cycle if the battery voltage falls below an internal threshold. The bqSWITCHER™ automatically enters sleep mode when VCC supply is removed.
  • High-accuracy voltage and current regulation
  • High-side battery current sensing
  • Battery temperature monitoring
  • Automatic sleep mode for low power consumption
  • Reverse leakage protection prevents battery drainage
  • Thermal shutdown and protection
  • Built-in battery detection
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
