I2C Controlled Single Cell Chargers with 5.1V Boost Operation: bq24195/2.1A and bq24195L/1A


Design files


bq24195 and bq24195L are fully integrated 4.5A charging / 2.1A boost  and 2.5A charging / 1A boost for power bank applications. TIDA-00036 is to demonstrate bq24195 and bq24195L single chip solution for fast charging, synchronous boost on-the-go (OTG) operation with high efficiency and low BOM cost.

  • Fast charge: up to 4.5A (bq24195)/ 2.5A (bq24195L) charging current to support high capacity battery pack
  • Battery boost operation: long battery run time with 90% OTG efficiency
  • Input voltage dynamic power management to support third party adapters
  • Enable compact 2.1A or 1A power bank design with Integrated FETs and shared buck/boost inductor
  • D+/D- USB detection and compatible to USB BC1.2

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
