產品總覽

The BQ24125RHLR is a single chip switchmode Li-ion and Li-polymer Charge Management IC with enhanced EMI performance. The bqSWITCHER™ series offers integrated synchronous PWM controller and power FETs, high-accuracy current and voltage regulation, charge preconditioning, charge status and charge termination. It 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. It automatically restarts the charge cycle if the battery voltage falls below an internal threshold and automatically enters sleep mode when VCC supply is removed.
  • Enhanced EMI performance
  • 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.
